Hi, I'm swapping an RB25DET into my S14a. The engine is in and everything is wired up but the car isn't starting. It is turning over. Fuel is coming through the fuel lines. I've tried unplugging the MAF. I'm using the stock R33 ECU and I'm presuming the wiring is good as I've paid J's garage to do that harness for me. Any suggestions on what to check next?
