Re: [MBZ] 1994 E320 (M104) No-Start

The leak was on the high pressure side of the filter, where the fuel enters under pressure from the pump. Maybe the filter was plugged up and starving the injection system. Max Dillon Charleston SC Feb 23, 2020 4:36:46 PM Curley McLain via Mercedes : > Waytago! Well if the pressure is not

Re: [MBZ] 1994 E320 (M104) No-Start

Waytago!   Well if the pressure is not high enough to pop the inj spring, it would not start.  A leak will lower the pressure.  Air in the system IS compressible also. I think those things run at pressures in the range of Diesel injection. (mechanical) Max Dillon via Mercedes

Re: [MBZ] 1994 E320 (M104) No-Start

Maybe I've fixed this? Yesterday I diagnosed the fuel leak as poor seal at the fuel filter, which is next to the second fuel pump. Had a new filter, so installed that with new copper washers at the banjo fitting, fuel leak fixed. Car started with no issues about 7 or 8 times (other than the

Re: [MBZ] 1994 E320 (M104) No-Start

The cars I've had with electric fuel pumps they run for a couple seconds when the key comes on and then shut off until the car is started. Which reminds me I need to change the fuel filter on my Jetta. Put in the new filter, turn on the key, wait while the pump cycles, repeat a couple times

Re: [MBZ] 1994 E320 (M104) No-Start

Well I bought some starter fluid, and then immediately tried it and the car started right up and stayed running. I wish I had tried to start without using the starter fluid to make sure it was still a "no-start" condition. Once started, the CE light was no longer lit. I put on my code reader at

Re: [MBZ] 1994 E320 (M104) No-Start

I've seen those for conventional spark plugs.  Evan have one somewhere, but I don't see how do you use then for the COP system? You could test for the current going  into the coil.  Wouldn't a bad coil show a code? Curt Raymond via Mercedes January 26, 2020 at

Easy to test the fp though, shoot a little go juice in, if it fires it's probably a fuel issue. Curt Sent from Yahoo Mail on Android On Sun, Jan 26, 2020 at 8:24 AM, Max Dillon via Mercedes wrote: I think it does, need to learn my way around this engine. No idea where that is, beyond

I think it does, need to learn my way around this engine. No idea where that is, beyond somewhere on the engine, front or rear. Fuel pump relay / fuel pump is another possibility. I think that relay is behind the battery? Max Dillon Charleston SC Jan 26, 2020 7:43:42 AM Dan Penoff via
