Hello all! Just installed an EJ257 STI engine into my 2002 WRX. I used the WRX harness and ECU, left the AVCS disconnected, swapped over the 2002 WRX TGV's, intake manifold, and Throttle body.
I have fuel, spark, compression (it's a BRAND NEW, ZERO mile engine), and air.. But the engine wont start. I can use starting fluid and it will start for a second or two, but then will immediately die out. If starting fluid isn't used then it will only turn over.
Any ideas, or advice on what could be wrong..?
