truck wont run after warmed up...no codes

sonic_superduty · Jun 12, 2012

Truck is a 03, It does run but you have to keep you foot on the pedal, take it off and it dies. I have recently replace the IPR & ICP... truck is a manual , and when you put it in gear and let out on the clutch it also wants to fall on its face, when it dies it is hell to get it fired up again. I also have not one code...:wtf:

What kind of pressure is the HPOP building?

Sounds like a high pressure oil leak.

try unplugging the ICP to see if it will run. did you rewire the ICP pigtail correctly? did you change the pigtail? it ran prior to these changes right?

Yeah I haven't done the pig tails yet, but it will run UN plugged, its just weird its fine in a free rev but falls on its face under a load

Get icp and ipr readings at idle, check fuel pressure as well

if it runs unpluged, you either have a bad icp again... or you need to change the pigtail out... my first one had oil about 10 inches up in the wires...make sure you cut it until there is no more oil....

could be a injector top blown off

And it would run fine with the ICP unplugged?

Sounds like it's time to do the pigtail!
