I have a 1986 porsche 944 non-turbo. I have recently replaced the camshaft gasket. I put everything back together and and tried to start it. Nothing happened. The motor would spin but would not attempt to crank. It also backfired heavily from the tailpipe. Someone told me that it was out of time. So i put it in time and tried to crank it. The samething happened. I bought a new timing belt and replaced it, thinking that would fix the problem. Still the samething. I have pretty much gave up on it. Nobody i know can give me any answers. CAN SOMEONE PLEASE HELP ME!!!!!!!????????
