Thank you for using just answer. My name is XXXXX XXXXX i will assist you today.
Do you have a scan tool?
WHen you turn the key on do you hear the fuel pump running under the drivers door?
Also when you turn the key on do you hear a clicking sound under the hood?
i just replaced the fuel pump two months ago and i do hear the clicking.
i have also replaced the oil cooler,egr cooler and the senser on the high pressure oil pump and the high pressure pump
What happened did it didnt start in the morning or after driving? Have you tried it again this morning
it ran fined last night but wouldn't start this morning
Is the icp on the valve cover or under the turbo? They changed in 04
under the turbo. i just replaced it a few months ago
did you replace the ipr as well?
what and where is the ipr?
The ipr is under the turbo as well. Its a regulator
i just changed the senser that screws into the top of the pump houseing. the icp is on the right side valve cover
the only thing left in the high pressure system is the hight pressure pump and injectors. They might be leaking. To be honest the next step requires a scan tool that can check icp pressure. We need to know if you are getting enough oil pressure. You need 500 min to start truck.
what if it is getting enough oil pressure what else could it be
Then you are looking at a fuel issue or even a ficm issue. If you have codes for all 8 injectors circuit low then you need a ficm. Make sure your filters are new.
ok thank you for your time and advise
No problem good luck
