  1. I'm positive I have the right relay. As for voltages, I get very low and unsteady voltage at the blue-yellow wire on the fuel pump (supply). Same goes for the connector under the seat where the black-red wire from the relay becomes the blue-yellow wire going to the pump. As for the pump motor, it has two wires in the connector. One is power supply, the other is a ground. I checked the pump to see if it grounded itself, and it does not. Only ground is through the connector. I though that might be the issue, so I provided an extra ground with a probe and some heavy gauge wire, but that didn't do anything. Whatever is going on, it's causing the pump relay to not close, keeping voltage from getting to the pump. Also, I keep seeing things online about an inertia switch. Do these cars have inertia switches? And if so, where would it be located?
  2. Did some more testing. Traced the purple wire from the relay to the computer. Continuity on the purple wire at both relay and ecu plugs. No short to ground. When I check voltage at that wire with everything hooked up, I get very low voltage with the key off and battery voltage with the key on... Seems like this is backwards, doesn't the relay need a ground on the switch side (fuel pump) and one on the control side (through the ecu)?
  3. Ok, so I have a 97 Subaru Legacy Outback with the 2.5. My wife drove it up to the gas station the other day, and when she came out it wouldn't start. I brought it home and started testing. Just replaced the fuel pump relay today with no effect. So here's what I have: - Battery voltage at the red wire on the relay connector at all times - Battery voltage at the yellow wire with the key on - Continuity to ground at the black wire below the blue-yellow wire on fuel pump connector - Continuity between the black-red wire on the relay connector and the blue-yellow wire on the pump connector, however with the relay installed, I can't get a voltage reading from the blue-yellow wire with the key on or while cranking - Pulled the pump, supplied power and ground and it started instantly - Pulled plug wire off the coil and cranked engine, has spark - I did not test anything on the purple wire at the relay connector since it runs directly to the ECU... With everything hooked up I can turn the key on, crank the engine, but the pump never turns on... Hoping someone on here might have some sage advice for me. I really need to fix my car before Tuesday so I don't get dropped from my classes.
