Have I no power at the fuel pump

Have I no power at the fuel pump

What kind of vehicle do you have so I can get a wiring diagram?

Customer: replied 1 year ago.
2001 dodge 2500 cummins 5.9
Expert:  -Brad- replied 1 year ago.

Thanks for the reply!!

I attached the wiring diagram and the ECM supplies 12v to the lift pump.. If you disconnect it and bump the starter do you have 12v on the Yellow/White wire?

No power at lift pump

WHat codes are active in the ECM?

Customer: replied 1 year ago.
P2016
Expert:  -Brad- replied 1 year ago.

Do you mean P0216?

Customer: replied 1 year ago.
Think so
Expert:  -Brad- replied 1 year ago.

Do you have anymore codes? Because the ECM supplies 12v to the lift pump and if it doesn't have any crank/cam codes then I would suspect a bad ECM. Do you have a scantool to monitor the cam and crankshaft signals to see if they are counting when you crank it? When you bump the starter the lift pump should run for 20 seconds.

Ecm whose not the problem still have no power to fuel pump
Expert:  -Brad- replied 1 year ago.

Before you replaced the ECM did you verify the crankshaft and camshaft were reading correctly in the ECM? Also do you know what code you are setting? Is it for sure a P0216 and if so is it the only code?
