So ive found my hard starting problem after sitting to be a fuel pressure loss. When i first go to start it up i have to prime the system by cranking a while. What could allow the pressure to bleed off overnight. I know its not the injectors leaking becuase the motor is not flooding its cranking just fine just no fuel to start. I wish i had more time right now to look at everything. Also this problem continues to get worse right now it takes cranking for about 4-5 seconds.

 

The only other thing it could be is the check-valve in the pump itself. If it's not going in the engine, or on the ground, then it has to be going back into the tank.



Maybe someone modded it. I've seen that as a flooding solution.
