I was sled pulling the other day and my truck cut off at the end and hasnt crancked back my fpr was going bad and i changed it out and it still wont crank it has a lift pump and my primer is hard as a rock and you can push it down at all where do i need to look it did have a fpr code
LLY: truck wont crank
- Thread starter ncdmax03
- Start date
Wont start or won't spin over? If it won't start then you can use a tech II . Perhaps EFI also will check PSI will cranking
If you have no codes then as stated great place to start is find a tech II or EFI and check fuel pressure when cranking over. Assuming you have checked obvious things like fuses and prime.
It would also be good to know with the LLY if it is an '05 or '06 model. Difference in electronic systems.
Check the turbo vane. If it died while running, there may be nothing left if you had it spooled up hard when the engine died. Doubtful, but possible.
Also on the early models, and because you said it had a lope, check the crank sensor reluctor wheel. It could have fallen off. Pull the crank sensor and put your little finger in the hole and feel for the pointers on the reluctor wheel. When they start to come loose, the motor can also have a lope to it. This is more likely if your truck is an early, '05, model. This was corrected somewhat in the later models.

It's a true lly, have you checked rail pressure while cranking? X2 on checking the reuctor wheel
