fjubain Posted December 17, 2009 Share Posted December 17, 2009 I have a 6.4l here that will not start when cold outside unless it is plugged in. Always retreived code p2291, frp pressure is 900psi. fuel filters where replaced, fuel not gelling, fuel was drained and refilled with fresh fuel. fuel pressure is 8 psi when concern occurs.I have followed the no start, hard start diag sheet in pced, performed ppt m and me.It leads me to hih ptressure pump replacement. After it starts it runs great. Is it possible for the fuel pressure control solenoid to stick cold, has anybody seen this before? Quote Link to comment Share on other sites More sharing options...
Jeff_ Posted December 17, 2009 Share Posted December 17, 2009 Go on a hard road test, then let it cold soak overnight, next morning before you try starting it remove the secondary fuel filter and see if the filter housing is empty. If it is, you have an air leak somewhere allowing the housing to drain and causing a big air bubble to go through the hp pump. Hotline told me a common place for this is the fittings at the HP pump, but I was lucky and just had a dry fuel filter lid o-ring that a lot of vaseline took care of. I also had a couple 6.4's gel last week. They only seem to gel in the primary filter housing which sucks to get to thanks to that wonderful wiring harness on the frame.

mchan68 Posted December 18, 2009 Share Posted December 18, 2009 I also had a couple 6.4's gel last week. They only seem to gel in the primary filter housing which sucks to get to thanks to that wonderful wiring harness on the frame.Only after the first fuel filter replacement. Subsequent fuel filter replacements are easier, because the wiring harness clip comes out easier. Just curious, what do you guys charge to replace these on a 6.4L? Do you charge any differently than a 6.0L? Quote Link to comment Share on other sites More sharing options...

dieseldoc Posted December 18, 2009 Share Posted December 18, 2009 [i also had a couple 6.4's gel last week. They only seem to gel in the primary filter housing which sucks to get to thanks to that wonderful wiring harness on the frame. My question is which brainiac decided this was a good place to mount the filter base. We all know how critical clean fuel is to the fuel system in these engines as well as the 6.0. So they mounted the fuel filter in the filthiest hardest places to get at they could think of. I just dont understand some things. Quote Link to comment Share on other sites More sharing options...

First off, our owner's own 9 other dealers (mostly Ford, couple GM/Chevy, couple Toyota, couple Dodge (some in the same locations). And they have the brilliant idea to 'menu' all the common repairs - diesel fuel filters at any dealership in our group - 0.6 - have argued this 'til I'm blue in the face with my SM - warranty pays 0.8!!!! So I generally try not to do them! Send them to the lube rack!!!! Secondly Quote: bleed the fuel system [/quote'] is completely uneccesary - if you have to bleed after filter replacement YOU DID SOMETHING WRONG!!!! Cycle the key 10 times after replacing both filters and it will NEVER air lock if everything is operating properly! Quote Link to comment Share on other sites More sharing options...

I'm saying our shop charges that extra .3 for that reason. I just see that extra .3 as me fighting that damn wire harness that likes to get in the way.

fjubain Posted January 9, 2010 Author Share Posted January 9, 2010 Just to let you guys know, the high pressure pump fixed it, vehicle asbeen running for over a week incold weather and all ok.So it is possible for the fuel pressure control solenoid to stick cold.
