Jumper the check engine connector-Batt to Fp and see what happens-it beginning to sound like EFI and COR relay. Check out the diagrams (Below). Please let us know what happens.

I am attaching the info on this relay and a guide that will help with testing it.

Also, attached below is the testing of the relay and location information.

If this relay tests out okay then we need to go to the circuit opening relay which directly controls the fuel pump. I included the info on this relay as well.

Let us know what questions you have. Thanks
