KOKO will work but you must have a scan tool that displays the TDCO value so you know if further adjustment is needed or if it is within parameters.

ok so after holding back on the truck, i finally attempted to remove a injector line. sprayed some wd 40 on her front left cylinder (on gas engine #1) came off with a little muscle, didnt break.

but with the line off i went to crank it i didnt see fuel being sprayed like id imagine it would, so i put a water bottle at the end of the line and cranked for about 10 sec. prob only put a teaspoon of fuel in the bottle. batteries where fully charged so she cranked over fast enough.

before i attempted to remove the line, while cranking she would spit and shudder and smoke was rolling(not running). even started for a sec then cut out. after i removed the line i couldnt get any spit or shudder for a while, seamed like the ip ran out of fuel. then she started to spit again but still no start

should add. when i first unhooked the line and turned it over i didnt see it but it look like it squirted a little but that was it, saw fuel dripping off the injector and return line

The fuel at the injectors is minimal and does just dribble if the line is separated from the injector.

Did you ever address the service throttle light problem?
It could be the root of what you have going on.

Just remembered the new pmd has a different plug so that won't work.

Couple things I'm remembering as I go on. One thing the speedometer will read a speed while cranking. It won't just jump up to 10 but while cranking it will build up like. 5mph per rotation. And there was some mystery fluid under the truck want to say it was about center where the engine and transmission mate
That fluid is more than likely fuel check FFM it has a in and a out as well as a O-ring in the bottom that will fail not sure of the size of the Oring but it more than likely can be had at a local parts store

Been a while just had time to mess with her. But she spits and sputters if you unplug the crank sensor with optical center plugged in you get no spitting and sputtering no smoke no nothing just doesn't try to fire. If you on plug the optical sensor with the crank position sensor still plugged in still no fire no smoke no spit and sputter.
