All- I've read every post on EFI / fuel pump issues but I can't figure this out after weeks of tinkering.
I've replaced the open circuit relay. Tested the EFI relay but still no fix.
Here's what I know/have done:
1. At the connection in the drivers rear wheel well the wires were corroded so I cut them to splice.
2. When I jump the FP and B+ at the diagnostic port in the engine bay there is no voltage getting to the wires in the rear wheel well going to the pump.
3. When I jump the FP and b+ on the open circuit relay(fuel pump relay) in the passenger kick panel, I get a solid 12 V between the green/red wire and the black / white wire in the rear wheel well coming off the wiring harness.
4. This is why I bought a brand new open circuit relay from Napa. I assumed it had to be the OCR bc jumping at that point put voltage back to the rear wheel well connection. Still no voltage when I installed the new relay and then jumped the FP and b+ in the engine bay though.
5. Wiring can't be bad since it gets 12v at the wiring harness in the rear wheel well when I jump it at the open circuit relay.
6. Fuel pump is good bc it runs when I jumped it directly to the battery.
Now what do I do? I'd appreciate any ideas. I have the FSM but no ideas on what else to do.
