So my truck ran great the last few days as I headed to the cabin 4 hours from home and tooled around up here last night to watch fireworks, etc.. Today it cranks/no start. Plenty of fuel pressure at the upper filter, so I don’t think it’s a problem between the tank and engine. I have a half tank of fuel, so it isn’t the obvious problem.
I’m running a SCT livewire TS+, using their canned tunes. Only code is p1000
KOEO:
ICP .5-1.5 psi
ICP duty cycle .14
VGT duty cycle 0.00
FICM main volts 49.0
Cranking:
ICP gets up to 287
ICP duty cycle .84
VGT duty cycle 0.00
FICM main volts 49.5
It has been rainy, humid, foggy. Hot in the day (near 90 is hot in northern WI). and low 60’s at night.
I remember reading ICP duty cycle should never read .15 or .85, but I don’t remember what it means if it does. I’m up here for 2 more days, there is a decent size town 30 minutes away I can get parts, and I have other vehicles I can take to get said parts.
There is a fair list of new parts on this truck, but not much related to fuel. I have been working on tracking down a “miss” when the truck is cold, all signs pointed to injector sticktion. I used an oil additive recommended by diesel tech Ron that nearly eliminated the problem.
I hope it’s something easy and not the HPOP....
Point me in a direction and I’ll go to work. FYI, I’m stranded here with my wife, parents, and 1 10 yo girl, and 4 13 yo girls. I don’t mind spending time in the garage!
