06 6.0 completely dead.

[JohnO]

My 06 with 97k miles was acting a bit funny over the last couple of weeks. I'd push on the pedal a little, and it seems it wouldn't pick up speed. Push on it more, and it would pick up, all of the sudden. Also has been taking longer to get it started. Not a lot, but seemed like it was three or four seconds of cranking to get it started, when it used to fire right up.

This weekend, was heading to town, it seemed a bit flat going up a hill, shoved on the pedal, it picked up power, then died completely. Coasted backwards home, wouldn't start. Batteries are getting a bit weak, so I replaced both of them. Cranks fast, but won't start. The next day, I thought - haven't changed the fuel filters in a long time, maybe they're clogged up, so I put in new ones, and there was fuel in the bowl for the primary filter when I took the old one out. Still won't start.

No check engine light, only one code came up, weak voltage on #1 injector, doesnt' sound like something that would keep it from starting at all.

Any ideas what to check next? Cranks great, but just won't fire. Sounds like it's just not getting any fuel.

What are you using to scan codes?

[Stoker0560]

sounds like maybe a HPO problem, maybe the STC? or does low, high pressure oil, throw a code, ive heard plenty of times the STC going out or blowing an Oring in the HPO system will stop the truck dead,

Ive heard the system can spring a leak, causing power loss, and then go completely out, giving you really cool looking anchor!

Sounds like your FICM is gone. Or it needs to be reflashed.

i guess when mine went bad i had long crank hard start problems, but the truck was never underpowered and never died, i took it in right away though.. good place to start anyways

Mine was hard to start and when it started it was like one of those rotary plane motors.It also ran fine until i stopped it and it was completely dead. The thing that hurt the most was the $517.00 tow bill.

I'm using an obdII reader, and all it reports is weak injector voltage on #1. Didn't think they used voltage on the PS injectors... Does the PS need a specific obdII reader?

I'm hearing blown HPOP O ring from other sources. Is this warranty service? I still have 3k miles left.
