Alright I have a bone stock 2000 dodge cummins that won't start. believe I have no fuel past injection pump. There are zero codes. All fuses and relays are good. Truck turns over but wont start.

 

Have you cracked lines at injectors to confirm that the Injector Pump is sending fuel to injectors?

Do you have fuel pressure gauge to monitor Lift Pump pressure? (If yes - what is the pressure when you turn key to start briefly and LP is operating? If No - WHY NOT??)

 

yep, crack the lines and make sure your getting fuel past IP... maybe it could be the lift pump.

 

Update I have half a tank and no fuel anywhere wtf about two weeks ago I installed a new rapitor frrp I can hear it run wondering if that's the problem

 

ya it might be... anyway u can test it?

 

just wondering if you resolved this problem as I am having same problem. have fuel to injector pump but none going to injectors. Also have low volume from the transfer pump.
