    02 wrx won't start after reflash

    Attempted to reflash my ecu. Everything seem to go well. Until I tried to start my car. Nothing seems to being working. Not even the fuel pump will kick on.

    Is it possible that I might have fried my ecu?

    Did you unplug the test connectors under the dash?


    What flash method did you use? AP? Open Source? Etc? What map were you flashing? Did you lose power at all during the flash?

    Unplugged the connectors after the flash.
    didn't lose power during the flash.

    Did you try flashing back your old map to see if it still works?

    Remove the negative battery cable and hold the brake pedal down for 30 seconds. The reattach the neg cable and try to start.

    This is my first time flashing the ecu. Previous owner had a utec but we removed it. The car was starting before but wouldn't accelerate. Found out it was dumping way to much fuel. Got a tactrix 2.0 cable, downloaded a stage1 map and used ecuflash.

    What mods does the car have? I you mentioned it was dumping too much fuel.. what injectors are on the car, and are they properly scaled?



    Bricked ECUs usually don't flash.. which is confusing because you can successfully communicate with the ECU and change maps, yet the pump doesn't prime. Maybe check the fuel pump relay in test mode? Something may have coincidentally burned out.
