Truck died, no start up after.

[ricearoni1024]

I was coming back from camping, slowing down at a stop light when the truck just suddenly died, the truck would not start again. No sputtering or any thing odd going on with the truck before hand. All temps were good, fuel pump is working...Any ideas? The only strange thing that happened before was my edge insight stop working after I changed my tune from matts srl to his tow tune. Any info is appreciated thank you!

probably your FICM ...this happened to me...check my last thread ..see if you have same symptoms

This. Check you FICM voltage.

NO..volts can be good and FICM still be bad..mine was 48 volts while on and cranking and it was still bad

Checking your voltage is still a starting point. When you have a no start it's all about eliminating potential causes.

Well I'm out of ideas. Today I checked out the ficm voltage it was 48v. The fuel pump is working and we removed the icp sensor and it still wouldn't start. Did give it a shot of ether and it definetly sounded like it wanted to start. But when I am cranking it there is no black smoke coming out. I'm out of ideas and think I might have to get it towed to a shop.

do you have AE or another good scanner? Need to know if your ficm/cam/crank sensor is syncing during cranking. If you're not getting any smoke when trying to start, and the FICM checks out at 48 volts, it sounds like the injectors aren't getting enough oil pressure to fire-when you turn the key on do they alll cycle? Check the no start checklist, measure voltage across the ICP sensor while cranking. Anything .8volts and over and it has enough oil pressure to start. If you have a scanner, monitor the following PID's.

FICM SYNC
CMP/CKP SYNC
ICP FILTERED (psi)
ICP COMMANDED (psi)
IPR DUTY CYCLE
ENGINE RPM

when cranking the ficm sync and cmp/ckp sync should switch to YES, or switch from 0 to 1.
ICP should be at least 500psi to start, and if it doesn't, IPR duty cycle should increase as icp pressure does. If ICP doesn't increase as IPR duty cycle does, you may have a hpo leak. You need to be turning around 200rpm to get the engine to fire.

also, pull the IPR out and check for a damaged screen/metal on it. That is a good indication that your HPOP is bad. Pull the oil filter, depress the button in the center and have a helper crank the engine. The bowl should fill within 10 seconds. I know you said the fuel pump is working, but have you checked pressure?

If you want, I can send you the procedure for monitoring engine RPM while cranking without a scanner, You'll need a DVOM that measure's in Hertz. PM me if you need help.
