No power to fuel pump relay. Please help

Guys, Im not getting any power to my FP relay. I checked the red wire and its 0 v. Checked the fuel pump fuse by the battery and it looks good. Can anyone help me troubleshoot this?
Any help greatly appreciated, im really trying to fix this today.

Re: No power to fuel pump relay. Please help

The ECM only turns the pump on for a few seconds after the key is put in run and after that only keeps the pump on when it sees the distributor inputs. Are you not getting voltage during crank and that 2-3 second burst after run? Did you try just swapping the relay with one of the others to eliminate the possibility of a bad relay?

Re: No power to fuel pump relay. Please help

I had the multi meter set to amps, my mistake. I have power at the fuel pump. Relay is working correctly. Pump doesnt prime, its dead. Im really surprised becuase it died out of nowhere and i swapped the fuel pump 3 months or so ago. Im warrantying out the pump today will update.

Any ideas why the fuel pump would have such a short life?

Thanks all

Abrasive debris inside the tank. Corroded in-tank wire harness. Plugged fuel filter. Communist Chinese fuel pump.
