Is there a fuse that controls the ECM? If so does anyone know the fuse number and location? 2002 2500 5. 9 Automatic transmission. .

Thank you..... Can a defective ASD relay prevent the lift pump from operating???

I don't think so, but it can't hurt to check. Swap it out with another known good relay and see.

If you haven't already... you can swap same relays in box... just make sure you keep track of suspected bad relay. The ASD relay is controlled by Fuse 6 in the PDC.

Did not solve the issue... This is beyond frustrating. .
