420a won't start

[Jeremy L]

Ok so here it goes, I have a 95 Talon 420a. The problem started about a week ago when I traded my Bmw for the Talon. I was told it only needed a tune-up and had a small oil leak coming from the back under the intake manifold somewhere. It started and ran but, the idle was rough. When I got it home I decided to use SeaFoam to clean it up before I did a whole tune-up, I poured 1/3 of the bottle in to the crankcase, a 1/3 into the gas and let the engine suck up the remaining amount, all seemed to be fine the engine sucked it all up and shut down. I waited about 30 minutes before I tried to start it back up and let it do it's magic but, nothing it just cranked and cranked. Ok fine fouled out the plugs no big deal right. Changed the plugs, wires and oil, tried to start it again, nothing just cranks and cranks. By this time I'm thinking maybe the oil leak was coming from a blown head gasket and the seafoam was just to much for it to handle so I compression tested it. Cyl #1 90psi Cyl #2 35psi Cyl #3 80psi Cyl #4 90psi blown head gasket right. Tear it all down replace the head gasket, got it all back together hoping it would start this time but, to no avail. I went back through it to make sure it was timed correctly, firing order was correct and all electronics and vaccum hoses were on. Everything looked good but it still wouldn't start. Now it's throwing codes P0351 Ignition coil A primary/secondary circuit malfunction, P0352 Ignition coil B primary/secondary circuit malfunction, P1391 manufacturer controlled ignition system or misfire. This is where I'm stuck, I changed the coil pack, wires and plugs again and still nothing. I've tried erasing the codes, resting the ecu and starting fluid. I'm running out of idea's and getting really frustrated with this fucking engine. Any help is greatly appreciated.

Thanks

This is why you're getting the last code. (P1391)

CODE 157 THROTTLE POSITION DOES NOT AGREE WITH MAP

Check camshaft position sensor, crankshaft position sensor connector and PCM connector. If connectors are okay, check cam sync signal and crank reference signal. See CODE 01: NO CAM SYNC SIGNAL AT PCM and CODE 40: NO CRANK REFERENCE SIGNAL AT PCM .
