Hey all....
99 2500 auto 4x4......

I had to finally replace my factory stock in tank lift pump....it killed inj.pump too.
I had a good unit here, installed it, And primed fuel thru to all injector lines...I have fuel to all injectors thru the lines....But even after 2 hrs of cranking I have no fire...
I tested IP for power from relay, and that is there....
No Codes at all...?

I looked in my manual and there is a fuel shut off signal pin 5 (LB-RD) on IP from ecm...could this be a bad wire...? is it hot or neg in key on mode...?

Thanks for any info,
John in Oregon.

 

Have you tryed starter fluid

 

I highly recommend against using ether / starting fluid.

If you still have a grid heater it's asking for trouble.


So to make sure I'm reading this correctly, you have fuel to all the injectors at the injectors themselves? Can you see the fuel pulsing out if they are somewhat loose when you turn the engine over?
