Re: [MBZ] 1984 500SEL - HELP!!
I always try to take a copy of the CL ad with me. If there is a serious disconnect between it and the actual car, I ask the seller to read it to me and point out the attributes they describe in the ad. In this case the seller said the car had been garaged all of its life. The roof paint was badly faded and the clear coat was gone. I asked him if he looked at this car would he believe it had been garaged all of its life. That was when I got the, It's a $1000 car, what did you expect? I told him what my expectations were that I expected people to be truthful, and that I thought that was fair and realistic. But it was garaged all of its life! I just turned and left at that point. There was no reason to continue. He said nothing as I left, I'm sure because he knew I was right. My search continues.

Thanks, Peter. What about the O-ring on the fuel pressure regulator in the side of the fuel distributor? My research shows that it can also be an issue, especially in cars where the fuel system has been crudded up. Dan Sent from my iPad On Jul 21, 2014, at 11:34 PM, Peter Frederick via Mercedes mercedes@okiebenz.com wrote: The leaking points are: fuel distributor to throttle body boot (buried on that car, you have to remove the manifold I think, but you have to anyway, see point #2) seals between intake manifold halves (this is an issue for all the V8s of that design type) Idle control valve hoses Injector seals Injector holder seals (bet you didn't even know they existed, eh?). On the M103 there is a plastic sleeve the injector fits into, and they have an o-ring in a slot on the outside to seal with the manifold. They go bad, and replacing the injector seals doesn't fix the issue. Typically all these must be replaced together, so its better to pull the manifold and do it all at once. The throttle body to fuel distributor boot bolts to the fuel distributor, so it all has to come out. Makes a big improvement in running and throttle response when you get it all sealed up. Another point to check is a sticky fuel distributor air flap pivot or plunger seal. If the flap does not move very freely with light pressure and spring back up to the idle stop by itself if depressed, you need to clean it and maybe pull the plunger and clean that. Once in a while the plunger seal gets leaky or drags too much, in either case mixture control is erratic and you get running problems.

On Jul 21, 2014 5:37 PM, Dan Penoff via Mercedes mercedes@okiebenz.com wrote: Finally heard back from the owner. Here's what he tells me: He got the car from the original owner. It had been parked for a couple of years after being run out of fuel. Wouldn't start or run when he got it. He replaced the fuel pump and filter and put fresh fuel in the tank. Fuel pump builds up pressure and turns off. Car will start and idle, but when you attempt to drive (load) the engine, it dies. He thinks the fuel strainer may be clogged up, but isn't interested in putting any more time into it. He says the hose from the strainer to the pump looks a little rough, and he's wondering if there might be some air leaks there. He got the car from the original owner either for free or very little from what I can tell, so it has just been a project to tinker with. He doesn't know MBs and seems obsessed about the original owner paying more than $60,000 for it new in 1984!! This does not seem to be an effort to pump up the price, just some sort of awe that a car would have cost that much in the day. I was going to run over to Harbor Freight and pick up a fuel pressure tester, but theirs says it doesn't work on Bosch or CIS-Jetronic. Is this the case? http://www.harborfreight.com/fuel-injection-pump-tester-92699.html It definitely sounds like a fuel delivery issue, as he says as they have tinkered with it there have been times when it could be driven at 20-30 MPH without a problem, then after being parked for a day it wouldn't do more than idle, that is, when loaded it would stumble and miss. I'm still going to take a jumper for the fuel pump relay, but I don't think that's the issue. Interior is said to be very good, with the stitching on the top of the back seat coming loose (nothing new there) and the exterior having a nickel-sized spot of rust bubble in front of the passenger side rear wheel well. Let's hear those ideas, guys! I nee some direction so I'll know what to look for when I get up there tomorrow night! Thanks!

It had the proper fittings to connect to the steel lines. You have to connect in a couple of places to test the system properly, not just output pressure from the pump. The instructions that came with the gauge set were adequate for testing the system. IIRC, I also bought a book on the CIS system that was very handy. Peter can correct me if I'm wrong (working from 25 year old memory here), but IIRC you hook the gauge, which includes a shutoff valve, to two places on the distributor, one near the inlet and pressure regulator and the other on top. With the valve open, it reads control pressure, with the valve shut, it reads the regulated fuel pressure. It's rather simple to pull the shims, spring, and ball to clean the regulator.

I always connected a CIS gauge in line with the warm up regulator. See the work instruction here: http://www.startekinfo.com/StarTek/outside/11883/PROGRAM/Engine/107/M116_38/07.3-120.pdf In checking the car for possible purchase, I'd check movement of the air flow regulating plate on the fuel distributor. It should move smoothly when pressed down and return back to its idle position by itself. Ideally, do this with the fuel pump jumpered. You can hear the injectors scream when the plate is pushed down. (But don't do this too much or you risk flooding the engine). Since the car has sat for a while, I'd guess there are fuel distributor issues. Fuel pressure and vacuum leaks are also a good to investigate. Most likely with the age of the car and lack of care its received, theres probably more than one thing wrong. The Delorian guy in Texas is a great source for rebuilt fuel distributors, btw.

Just got home. Long story short, this car was not as described. The paint was thrashed, for one. There is no doubt in my mind that the fuel system was clogged up. The engine would idle but not carry load. You could press your foot to the floor and it might go to 3000 rpm, but shortly after would die off with your foot still on the floor. Interior wasn't bad. Trunk had a leak somewhere - I could smell the mold. Gotta love CL sellers. I took the guy to task over the description and all he could say was, What do you expect for a $1200 car? I told him I expected people to be truthful in their description. That was pretty much it. Other than a couple of hours of my time and maybe $20 worth of fuel I'm out nothing.

Just got home. Long story short, this car was not as described. The paint was thrashed, for one. There is no doubt in my mind that the fuel system was clogged up. The engine would idle but not carry load. You could press your foot to the floor and it might go to 3000 rpm, but shortly after would die off with your foot still on the floor. Interior wasn't bad. Trunk had a leak somewhere - I could smell the mold. Gotta love CL sellers. I took the guy to task over the description and all he could say was, What do you expect for a $1200 car? I told him I expected people to be truthful in their description. That was pretty much it. Other than a couple of hours of my time and maybe $20 worth of fuel I'm out nothing.

See the work instruction here: http://www.startekinfo.com/StarTek/outside/11883/PROGRAM/Engine/107/M116_38/07.3-120.pdf In checking the car for possible purchase, I'd check movement of the air flow regulating plate on the fuel distributor. It should move smoothly when pressed down and return back to its idle position by itself. Ideally, do this with the fuel pump jumpered. You can hear the injectors scream when the plate is pushed down. (But don't do this too much or you risk flooding the engine). Since the car has sat for a while, I'd guess there are fuel distributor issues. Fuel pressure and vacuum leaks are also a good to investigate. Most likely with the age of the car and lack of care its received, theres probably more than one thing wrong. The Delorian guy in Texas is a great source for rebuilt fuel distributors, btw. Hes just a bit quirky to deal with http://www.specialtauto.com/mercedes-parts/index.html Good luck!

[MBZ] 1984 500SEL - HELP!!
Finally heard back from the owner. Here's what he tells me: He got the car from the original owner. It had been parked for a couple of years after being run out of fuel. Wouldn't start or run when he got it. He replaced the fuel pump and filter and put fresh fuel in the tank. Fuel pump builds up pressure and turns off. Car will start and idle, but when you attempt to drive (load) the engine, it dies. He thinks the fuel strainer may be clogged up, but isn't interested in putting any more time into it. He says the hose from the strainer to the pump looks a little rough, and he's wondering if there might be some air leaks there. He got the car from the original owner either for free or very little from what I can tell, so it has just been a project to tinker with. He doesn't know MBs and seems obsessed about the original owner paying more than $60,000 for it new in 1984!! This does not seem to be an effort to pump up the price, just some sort of awe that a car would have cost that much in the day. I was going to run over to Harbor Freight and pick up a fuel pressure tester, but theirs says it doesn't work on Bosch or CIS-Jetronic. Is this the case? http://www.harborfreight.com/fuel-injection-pump-tester-92699.html It definitely sounds like a fuel delivery issue, as he says as they have tinkered with it there have been times when it could be driven at 20-30 MPH without a problem, then after being parked for a day it wouldn't do more than idle, that is, when loaded it would stumble and miss. I'm still going to take a jumper for the fuel pump relay, but I don't think that's the issue. Interior is said to be very good, with the stitching on the top of the back seat coming loose (nothing new there) and the exterior having a nickel-sized spot of rust bubble in front of the passenger side rear wheel well. Let's hear those ideas, guys! I nee some direction so I'll know what to look for when I get up there tomorrow night! Thanks!

Re: [MBZ] 1984 500SEL - HELP!!
Maybe the hose is all buggered and is collapsing when fuel is pumped through it (here I am assuming the pump is sucking it from the tank) or has crap in it from sitting so long. The filter aspect would also be a good place to start. How hard would it be to get a mity-vac on a fuel line and see if you can pump some (sucking?) from the tank? Take along some generic fuel line, run it from the tank vicinity to the fuel pump and see if you can bypass the line? It most definitely sounds like a fuel starvation issue of some sort. I had a lawnmower do that, ended up cleaning the whole fuel system and carb to get it to run right. I wonder too if the tank has gotten rusty from sitting in a humid environment, using crap ethanol fuel, etc. and that has clogged the filter? --R (no expert on Benz vergassers) On 7/21/14 5:37 PM, Dan Penoff via Mercedes wrote: Finally heard back from the owner.

One other thought -- a jug of gas with a hose in it, pump some fuel from there? Here again I am assuming the fuel pump sucks the gas and is somewhere near the engine.

Any simple tests I can perform to determine if this is the case?

Re: [MBZ] 1984 500SEL - HELP!!
When I started having trouble with the '78 450SLC running right, I bought a CIS testing kit from JC Whittney, I don't remember that it was very expensive at the time. It had the proper fittings to connect to the steel lines. You have to connect in a couple of places to test the system properly, not just output pressure from the pump. The instructions that came with the gauge set were adequate for testing the system. IIRC, I also bought a book on the CIS system that was very handy. The fuel pump and filter is under the fuel tank at the rear of the car. There are several hoses there, but if they are leaking, you'll see fuel . . . When the M117 engine in the 450SLC stopped running altogether, I disassembled it to find out what was wrong, and found almost all of the rubber bits in the intake system (there are a LOT of them) were hard, brittle, and leaking, making proper mixture impossible to attain and hold. The 500 engine in that car is the aluminum block version of the iron 450 engine, and I'm fairly certain that it's almost the same otherwise.

Re: [MBZ] 1984 500SEL - HELP!!
The leaking points are: fuel distributor to throttle body boot (buried on that car, you have to remove the manifold I think, but you have to anyway, see point #2) seals between intake manifold halves (this is an issue for all the V8s of that design type) Idle control valve hoses Injector seals Injector holder seals (bet you didn't even know they existed, eh?). On the M103 there is a plastic sleeve the injector fits into, and they have an o-ring in a slot on the outside to seal with the manifold. They go bad, and replacing the injector seals doesn't fix the issue. Typically all these must be replaced together, so its better to pull the manifold and do it all at once. The throttle body to fuel distributor boot bolts to the fuel distributor, so it all has to come out. Makes a big improvement in running and throttle response when you get it all sealed up. Another point to check is a sticky fuel distributor air flap pivot or plunger seal. If the flap does not move very freely with light pressure and spring back up to the idle stop by itself if depressed, you need to clean it and maybe pull the plunger and clean that. Once in a while the plunger seal gets leaky or drags too much, in either case mixture control is erratic and you get running problems.

HF has a Cis kit also, it's the $100 One Sent from my iPhone On Jul 21, 2014, at 10:15 PM, OK Don via Mercedes mercedes@okiebenz.com wrote: When I started having trouble with the '78 450SLC running right, I bought a CIS testing kit from JC Whittney, I don't remember that it was very expensive at the time. It had the proper fittings to connect to the steel lines. You have to connect in a couple of places to test the system properly, not just output pressure from the pump. The instructions that came with the gauge set were adequate for testing the system. IIRC, I also bought a book on the CIS system that was very handy. The fuel pump and filter is under the fuel tank at the rear of the car. There are several hoses there, but if they are leaking, you'll see fuel . . . When the M117 engine in the 450SLC stopped running altogether, I disassembled it to find out what was wrong, and found almost all of the rubber bits in the intake system (there are a LOT of them) were hard, brittle, and leaking, making proper mixture impossible to attain and hold. The 500 engine in that car is the aluminum block version of the iron 450 engine, and I'm fairly certain that it's almost the same otherwise.

It had been parked for a couple of years after being run out of fuel. Wouldn't start or run when he got it. snip I was going to run over to Harbor Freight and pick up a fuel pressure tester, but theirs says it doesn't work on Bosch or CIS-Jetronic. Is this the case? http://www.harborfreight.com/fuel-injection-pump-tester-92699.html It definitely sounds like a fuel delivery issue, as he says as they have tinkered with it there have been times when it could be driven at 20-30 MPH without a problem, then after being parked for a day it wouldn't do more than idle, that is, when loaded it would stumble and miss. I'm still going to take a jumper for the fuel pump relay, but I don't think that's the issue. Interior is said to be very good, with the stitching on the top of the back seat coming loose (nothing new there) and the exterior having a nickel-sized spot of rust bubble in front of the passenger side rear wheel well. Let's hear those ideas, guys! I nee some direction so I'll know what to look for when I get up there tomorrow night! Thanks!
