fjubain Posted January 15, 2009 Share Posted January 15, 2009 Very cold snap here, 30 below for two days, i have two units that quit on road with these code p0087 and p2291. Fuel was gelling, added ford gel improver and vehicle were in shop all night , re fill with fresh fuel , clear code all ok this morning. High pressure pump pressure back to normal and low pressure ok. Could this have cause any damaged or should i look for any other things, note fuel filters also have been replaced.

Keith Browning Posted January 15, 2009 Share Posted January 15, 2009 Fuel gelling will cause a lack of fuel pressure which the 6.4L does not tolerate. So, I doubt the engine would have run at all or not at all leaving little chance for fuel pressure related damage to occur. I am not aware of any known issues with this common rail system regarding pressure as I stated... perhaps someone else can add to this. I wouldn't worry about it at this point.

Mekanik Posted January 15, 2009 Share Posted January 15, 2009 I've got one too, and its -15f here. The truck will stall and then start if you let sit. I'm looking into it. Quote Link to comment Share on other sites More sharing options...
Mekanik Posted January 15, 2009 Share Posted January 15, 2009 I just got off the phone with hotline. They think I have a bad PCV or VCV solinoid. He said that is common with a 6.4 that will stall when warm and re-start after sitting. His suggestion is to get the engine hot, and then check the resistance of the PCV and VCV solinoids. If it is over 10 ohms I have a bad solinoid. He said that the PCM will not store a DTC until the resistance is over 100 ohms. I hope this helps. /forums/images/%%GRAEMLIN_URL%%/cheers.gif Quote Link to comment Share on other sites More sharing options...
fjubain Posted January 16, 2009 Author Share Posted January 16, 2009 I re road tested both trucks and ran fine, send them out and have not called back yet,thanks for the heads up. Quote Link to comment Share on other sites More sharing options...
Mekanik Posted January 16, 2009 Share Posted January 16, 2009 Well I got that 6.4 really really hot and checked the PCV and VCV. The resistance was 3.4, 3.9 ohms. I think those solinoids are fine. I ended up putting some anti-gel in the tank, and road tested it. I'm thinking it was just gelling fuel. I never did duplicate the problem. At least its Friday. /forums/images/%%GRAEMLIN_URL%%/drinkingdude.gif Quote Link to comment Share on other sites More sharing options...
Aaron Posted January 17, 2009 Share Posted January 17, 2009 -24 here, no problems that I have seen yet. Knock on wood, I will go to head out here in a few minutes and my truck won't start. Quote Link to comment Share on other sites More sharing options...

Aaron, I think the peolpe where you live might be a little better educated about using anti-gel products in thier diesels. You Canadians are probably still driving around with the windows down in -24. Quote Link to comment Share on other sites More sharing options...
Aaron Posted January 18, 2009 Share Posted January 18, 2009 I had to move the HOT/COLD selector a little more out of the blue range and a little more into the overlapping blue/red range, you know, in the middle? I think they call it 'Warm'? Still haven't cranked the windows up yet. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted January 18, 2009 Share Posted January 18, 2009 Hey, I would appreciate it if you Canuckians would keep your arctic air up there with you! Man it has been cold here lately... well, maybe it's t-shirt weather for you guys but for me it's cold! Quote Link to comment Share on other sites More sharing options...

exmod110 Posted January 18, 2009 Share Posted January 18, 2009 We had -39 early last week and now it's 0 3 days later!!! Time to get the shorts!!! Quote Link to comment Share on other sites More sharing options...
Tony302600 Posted January 22, 2009 Share Posted January 22, 2009 i had a friend call me bout his 6.4L that stalled last week when we had the stupid cold. Told him to check fuel filters (he forgets that stuff) told meit was gelled up. Told him to put anti-gel and bring it to his shop to let it warm up over night. Worked like a charm next morning. This stuff has to happen up in canada doesnt it? Quote Link to comment Share on other sites More sharing options...
