Power fc issue - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I just got a power fc and installed it and my check engine light flashes the fuel pump relay clicks and the fuel pump doesn't prime. If I use my enthalpy ecu everything works fine it's a #62 ecu. If anyone has had this problem or knows what to do please let me know.

well if you have the hand commander it will tell you which relay is bad... in the swsensor/check in the settings

When I turn the key on and the commander won't leave the apex I logo screen

So 2 things either the PFC is fried or you have the wrong commander for the unit

The power fc works in my buddies car so it's not fried, and I have a blacktop sr and looked up the serial number and it's for a blacktop, I'm gonna have to do some wire chasing.

I had an old power FC once that wouldnt work with any commander (it looks roasted) but it would work fine in a car, plus I could connect using data-logit and tune it that way. Just never could run a commander.

Well the commander works on the ecu in my friends car so I think it's my wiring cause I found some splices about a foot away from the ecu harness so I might just order a new harness

I had a similar issue when I bought a used RB PFC. The commander wouldn't go passed the APEX'i logo. After some research I found that PFC requires a good power source which isn't always good through the OEM harness. I found out what PIN in the harness gave power to the ECU and ran some wire directly from the battery to the pin. It worked after that.
