You say “no CEL’s lit” but the CEL should be on with key-on until you start the car…possibility that your PCM circuit has no power… > > 1. is your car AWD or FWD? > > 3)does your car have a factory alarm on it? > > Let me know those answers and I can whittle down the wiring for you for better diagnostics 🙂 I will have to check again tonight and let you know when i put he key to on. From my memory key on, I have a red battery light steady, and if IRC 2 other red icons, no CEL if I remember correctly. I will check in a few and report back. It is an AWD, 97 Legacy Brighton (bottom of the line edition) I dont have a tach either to see if the Crank pos and cam pos are sending anything when it cranks, I was told that the tach would react a little when you crank it. Brighton didnt even have a tach, so no way on the alarm! lol --- _[View the full topic](https://forums.speedlife.net/t/calling-subaru-people-fuel-pump-voltage-troubleshooting-help/249872)._
