My truck gelled up yesterday. It was -5*. At least I think that is what happened. It started running rough, bucking and shaking hard, then died. I had additive in it, apparently not enough. I drained the fuel bowl, I drained my pre-pump filter, I put 911 in it, and I replaced the fuel filter. I could get it to start, but it would run for about 4-5 seconds then fall on its face and die again. I couldn't get it to stay running. I towed it home to the heated shop. Tried to start it the next morning, and she won't fire. It doesn't even try to fire off.

My fuel pump is sending up a nice, steady, clean stream of fuel.
My filter is brand new.
I unplugged IPR (didn't change anything).
Tested PCM in other truck, works fine.
Ran buzz test (all 8 buzz strong).
Swapped CPS with another truck, works fine in other truck.
Unplugged fuel bowl heater, fuse wasn't blown though.
I don't know what to check next.

 

yup, I'm an idiot. I plugged in AE, graphed my ICP... hardly builds... checked my oil... below the dipstick.... what a dipstick move

 

Well, at least your on the road again - get ready, it's gonna be another cold & nasty night. What did they say -13F with wind chill from 30-40 below zero?

Park her indoors if you can!

 

On the other hand it was a quick definite fix.

 

don't feel bad...got me last week too..

 

At least it wasn't any of the things you thought it wasn't

 

Yeah. Its gonna be a cold one. Winds tomorrow are expected to be upwards of 45mph....

Wood stove heated shop for this thing.

 

True... but I have to figure out where all the oil went. After my truck thawed out overnight there were pools of oil underneath each exhaust union and a puddle at the tip. Is that a sure sign of a turbo going bad?
