[Biofuel] Chevy diesels
Hello everybody in the New World and others. I have an aquintance who is running his Chevy 6,2 litre truck on biodiesel, and he experiences mysterious engine stops etc. The car will start immedeatly again after a few seconds. He suspects it to be a computer bug in the injection system.Anybody with similar problems ?

Re: [Biofuel] Chevy diesels
Hmmm. I didn't think that computers were introduced till the second or third year of the 6.5 liter versions. All the 6.2's were mechanical injection. I've got a friend with a mechanical 6.5 that he runs on B100, and except for gelling issues in the winter, he says it has always run fine. Sounds like a fuel supply issue. Maybe the lift pump is weak and the injection pump is momentarily exhausting the supply of fuel in the filter. A clogged or gelled filter can also behave like this -- fine for the first 10 seconds of hard acceleration up a hill, then kaput, as the flowrate demanded by the injection pump exceeds the flowrate through the partially clogged filter. And if you let it set for little, the filter will re-fill, and it runs fine again. On my mitsubishi truck, I had to change the filter about 4 times over the first year when I switched to biodiesel. Around 1000 miles, 3000 miles, 6,000 miles, and 10,000 miles. On 4/23/07, Jan Warnqvist [EMAIL PROTECTED] wrote: Yes, he has.

Re: [Biofuel] Chevy diesels
I would agree that it's a fuel supply issue as well. I had the same problem, but not with biodiesel. (I don't yet have a setup to make any.) I'm not sure if you have a sock-type filter in the fuel tank, (I think all cars should have them!!) but you should check that and all the lines up to the filters and all the way to the injection pump. It can be a faulty pump, but with those symptoms I would think a restriction is more likely. If the supply pump was pulling a vacuum against a restriction it would cause exactly what you describe and then restart when the pressures had equalized in the fuel lines. All 6.2 engines that I've ever heard of were purely mechanical injection. It's easy to check. Look at the injection pump. It should have 3 wires going to it - one pink that's the fuel cut-off solenoid and two green that are the cold idle connections. If there's a bunch more wires (something like 8-12 I think) then it could be a computer, but that would be the first I heard of. I guess speaking of electrical it could even be that shut-off solenoid or a connection to it, but I doubt it. I've only seen them work consistently or fail completely. (Not that my experience is all that exhaustive.) Good luck! Erik On 4/23/07, Zeke Yewdall [EMAIL PROTECTED] wrote: Hmmm.

Re: [Biofuel] Chevy diesels
Yep I have the exact same symptoms when I add too much BD to the mix in cold temperatures. At idle and low acceleration it is fine but when injection volume is increased ( hill climbing or hard accel) the flow through the filter can't keep up. It is not clear from you message Jan if this is what is happening with the chevy. I get a feeling it is slightly different? Joe Zeke Yewdall wrote: Hmmm.

I have an aquintance who is running his Chevy 6,2 litre truck on biodiesel, and he experiences mysterious engine stops etc. The car will start immedeatly again after a few seconds. He suspects it to be a computer bug in the injection system.Anybody with similar problems ?

Re: [Biofuel] Chevy diesels
Hello Keith. He is in Sweden on rapeseed BD. But, as far as I remember, somebody in the US wrote about some similar problems with his Chevy. - Original Message - From: Keith Addison [EMAIL PROTECTED] To: biofuel@sustainablelists.org Sent: Monday, April 23, 2007 4:43 PM Subject: Re: [Biofuel] Chevy diesels Hello everybody in the New World and others.

Re: [Biofuel] Chevy diesels
sounds like fuel to me i have a 04 dodge with the cummins engine the lift pump was mounted on the filter housing. after 2 miles it went south . the dealer had a retro fit system for it that is mounted it the tank. it is easier to push fuel than pull it. not sure where chevy has the lift pump but bio has heavyer viscosity thn dino. add a cold morning to that and wala. good luck with the problem.

I had the same problem, but not with biodiesel. (I don't yet have a setup to make any.) I'm not sure if you have a sock-type filter in the fuel tank, (I think all cars should have them!!) but you should check that and all the lines up to the filters and all the way to the injection pump. It can be a faulty pump, but with those symptoms I would think a restriction is more likely. If the supply pump was pulling a vacuum against a restriction it would cause exactly what you describe and then restart when the pressures had equalized in the fuel lines. All 6.2 engines that I've ever heard of were purely mechanical injection. It's easy to check. Look at the injection pump. It should have 3 wires going to it - one pink that's the fuel cut-off solenoid and two green that are the cold idle connections. If there's a bunch more wires (something like 8-12 I think) then it could be a computer, but that would be the first I heard of. I guess speaking of electrical it could even be that shut-off solenoid or a connection to it, but I doubt it. I've only seen them work consistently or fail completely. (Not that my experience is all that exhaustive.) Good luck! Erik On 4/23/07, Zeke Yewdall [EMAIL PROTECTED] wrote: Hmmm.

Maybe the lift pump is weak and the injection pump is momentarily exhausting the supply of fuel in the filter. A clogged or gelled filter can also behave like this -- fine for the first 10 seconds of hard acceleration up a hill, then kaput, as the flowrate demanded by the injection pump exceeds the flowrate through the partially clogged filter. And if you let it set for little, the filter will re-fill, and it runs fine again. On my mitsubishi truck, I had to change the filter about 4 times over the first year when I switched to biodiesel.

Re: [Biofuel] Chevy diesels
A blocked fuel filler cap vent can give these problems too. regards, Ian - Original Message - From: Joe Street To: biofuel@sustainablelists.org Sent: Tuesday, April 24, 2007 2:46 AM Subject: Re: [Biofuel] Chevy diesels Yep I have the exact same symptoms when I add too much BD to the mix in cold temperatures. At idle and low acceleration it is fine but when injection volume is increased ( hill climbing or hard accel) the flow through the filter can't keep up. It is not clear from you message Jan if this is what is happening with the chevy. I get a feeling it is slightly different? Joe Zeke Yewdall wrote: Hmmm.
