Pulled engine and tranny out to change clutch and to fix leaks and get things cleaned. I sprayed everything off with pressure washer even engine bay. I did my best to stay away fom ecu. I put it back together today, and installed a aluminium flywheel and clutch from TU. It will crank but not start, there is no spark and I dont think the injectors are firing. There is only a half volt signal going to coil pack and the only codes I get are 12 53 55. Any ideas? I also redid engine timing a to th factory spec since I changed front main seal.
