Truck died while driving it had been running good up to the time it died. It will not restart with the exception of (I know it's bad)but it will fire with a small shot of starting fluid but dies after about 3 seconds. I have replaced the fuel pump, fuel filter, ICP, HPOP, CMP, CPS, changed the oil, dropped the fuel tank and checked the pick up screen, checked return fuel line no clogs, checked fuses, hooked to 3 different obdII scanners no codes. I put 100 lbs air pressure in ICP port in head held pressure could not hear any leaks. took the IPR apart and cleaned it. Does anyone have any ideas of what I'm missing here. Not only do we need our truck to run but this has become a mission to find out what's wrong getting very frustrated.

 

What is your actual icp pressure when cranking? Does your WTS light come on?

 

Haven't checked ICP pressure yet because I don't have a fitting that I need for my gauge should have that tomorrow and yes the wts light does come on.

 

Should be able to check it with the scan tool.

Have you check to see if theres oil in front cover.

 

I hadn't thought about the scanner to check that I will see if the scanners I have can do that tomorrow. do you know what the pressure should be.

 

500psi to start I've seen them start with a little less but not much.

 

Ok thank you that's what I thought it was suppost to be I will post on here when I get that tested.

 

icp pressure was 200 psi

 

Ipr could be stuck or high pressure oil pump is bad.

 

the ipr was bad replaced and runs great once again thanks for the help
