Well I only have 'til next wednesday to pass before the truck is given a forbid to drive.
I'm pretty sure that the problem is engine electrical...
It has gotta be related to the starting issue as well.
After sitting for about an hour it does the same thing every time now. Fails to fire right up and then takes a few turns to fire up, like if it gets flooded or something. The plugs doesn't look too wet though.
I replaced the coolant temperature sensor, no difference.
One other thing, we moved the TPS last summer. Turned it all the way to the right and the engine felt better then. It doesn't seem to make much difference where ever it's placed but I can hear the engine sound change a bit. Where should it be set? I checked the resistances from the pins and they were fine.
Otherwise I'm down to the injectors, cold start injector and fuel pressure regulator. Where should I start? I checked the FSM and the injectors seem to request some SST to test. How do I test the fuel pressure regulator? Any other ideas that could cause the high HC @ idle and the starting issues when warm and sitting for a while? Can't be that many things left to test, just gotta scratch them of the list one by one and hopefully not get broke in the mean time

Oh, and I'm not 100% sure the timing is perfect. The engine does feel like it's missing on idle.
is it 5 dgres whith shorted terminals and 10-14 w/o?
It does feel friscier when advanced beyond that
