i have a 97 powerstroke, 284k and still running strong . Now here's my problem, every morning when i go to start the truck, it skips, i have one dead cylinder. now i know this IS NOT glow plug related, or atleast im 99% sure. I tested the relay, the controller, and every glow plug including the harness and everything checks out, wait to start light comes on for only one second, but the relay stays on for about one minute in 60 degree weather. which i think is normal, i know they can stay on up to 2 minutes. But the glow plugs are working.

now what im thinking is, i have one injector thats not firing until the engine reaches around 150 degrees, i know the injectors become temperature sensitive when they get older, but i dont know which one it is. and they all tested out good ohm wise, so heres what im trying to do for my next step.
I want to unplug the engine oil temp sensor, and jump the harness side with a resistor, and do a cylinder contribution test. i have access to scanners. by jumping the harness side with a resistor, it tricks the computer to thinking that the engine is already at temp and i can do the test cold while its still skipping other than warm like your supposed to. the skip isnt present after the motor is at temp. otherwise i cannot find the skip unless it's cold.

anybody know the resistance value on the eot sensor??? its the sensor on the high pressure oil pump facing towards the back of the truck.

 

found the issue, one injector was installed with a hammer solenoid pack was cracked. also found one injector stuck open after experiencing a white smoke show.
