This post's a little long but hopefully it will give you guys some background info so you can help if you can. Thanks in advance guys!
I have a '94gt with 60k on DOHC motor. I've replaced the timing belt, all 3 timing belt covers, tensioner, pump, plugs, wires and crank angle sensor. Then a rag got caught on the rear cam gear and broke the cam angle sensor, so I had to replace it also. After installing all the new parts she started on the first turn. I killed it and restarted and she ran great until the motor started getting warm, then it started to miss, so I killed it, rechecked all the wires, hoses and water, but all looked good, so I restarted. As she got to operating temperature she started missing badly, then died and would not restart. I could smell gas so I checked the spark and I was only getting fire to 2 plugs (2&5). I thought the timing jumped so pulled her back apart and rechecked the timing and all the marks were right on the money. I figured it had to be the Power TR Unit! So I bought one from mykiss69(very cool guy) and he sent 2 units to me. No luck, tried both, still only getting spark to 2 & 5. I checked the diagnosis code and got code 23: TDC sensor (Which is the cam angle sensor). I thought that there was no way a new part could be bad, so I checked the volts at the harness connector: 12 volts, 5 volts, and ground. So I took the motor back apart and had them replace the cam sensor. I installed the new cam sensor and she started first try, then the same as above happened. I let her sit overnight and tried it again. I was back to only getting spark on 2 & 5.
Thanks for reading and anything you guys can think of will be appreciated.
