Hi Guys, I have just finished transplanting a 94 jdm wrx Gc8 half cut into my Gc6 impreza. I have transplanted everything from the halfcut engine ,g/box harness suspension, the only thing i re used is my dash top because it was in better condition. The Question I have is today I went to start it up for the first time it wouldn't fire up. I checked that I had fuel pump pressure, She definitely has spark as i pulled out a plug and earthed it and it is definitely sparking. there is power at the injectors and it cranks over but will only fire if i put a dribble of fuel in the plenum chamber through a vacuum line. Checked the maf sensor. And i am just about to Manually read the ECU codes of Rossco's post.

Any ideas ?
