fuel pressure loss PLEASE HELP
 

I have a 93 dodge cummins and it was running great and just died like it lost all its fuel so i replace the lift pump bled the injection lines and it was running great again took it out of the shop made it not even a km down the road and it died again we took it back to the shop bled the injection lines again was sure all the air was out and it once again was running great i let it idle at 1,000 rpm for about half an our shut it off and went out and started it multiple times the the day everytime with just a touch of the key it started just bang so i took it for a drive again and didnt even make it out of the yard and it died again and acts like its got no fuel does this mean my injection pump is gone?

I would check EVERY other possibility for air leaks before you tear into the pump. Make sure your not sucking air at the fuel heater (it's above the fuel filter), banjo bolts, quick connects, fuel line, and lastly the fuel tank. Sounds suspicous that it dies when the truck is moving, like something is loose. Might want to check the fuel shutoff solonoid wiring, good luck

thanks man turned out the wiring to the fuel shut off was real loose

Good deal! I know a few people who had a bad wire to the shut-off soloniod that caused a lot of headaches, glad ya got her goin
