Morning all new to the forum and impreza ownership. It's a 2003 wrx
Loved the car for the short time it lasted.
So here's whats happened, car was running one second turned it off went off came back and won't start.
Noticed fuel pump wasn't priming checked all fuses all OK.
So hooked a direct 12v to the pump and it runs so can't be the pump.
Tried to start the car whist the pump was plugged to the 12v still just turning over. Swapped the wires round incase it was blowing instead of sucking still nothing.
Really don't know what else to check
