Sounds like you're making progress. You have to make sure that you get fuel up at each injector. Just one injector with air can cause a problem. You need to determine what is the run position on you fuel solenoid. Can you disconnect the fuel solenoid wiring harness if there is an electrical problem. They usually default to run position with no power.further to my issue i pulled my primer off and tested it manually. it does pump fuel (doesn’t necessarily mean it will under pressure though). i also cracked the fuel lines to 1 and 2 while turning it over and fuel does drip out. i also cracked the bleed screw at the pump and primed it. fuel came out so i pumped it until there were no air bubbles in it either. still no fire. i suppose it could still be fuel solenoid huh? i don’t see any leaking spots on the fuel lines from what i can see lying in the gravel under my truck but that’s not a perfect inspection. can the solenoid be taken off with the pump on the truck or does the pump have to come off?
i’m pretty new to the diesel stuff. keen to learn not afraid to try just green.
