My 1991 sc will only start with the cam sensor unplugged. It usually starts on the second crank. I had two used ones then I got a new one and still the same issue.
With it plugged in the engine turns and then bangs as it stops. So bad that I thought the engine had internal issues until I unplugged the cam sensor.
I just installed a bhj harmonic balancer and a different timing cover due to a broken stock balancer and seized water pump stud.
The balancer is timed at 28 degrees after tdc. I did this by cutting a 1.3 inch long piece of masking tape as the instructions show. So 1.3 inches from tdc towards the drivers side.
Then I installed the synchronizer with the alignment tool pointed towards the front passenger side corner. It matched the picture I have from Mitchells manual.
Now I am at a loss. I have a spare DIS module and I installed that at my friends place. It ran ok but rough idle and then it stalled 20-25 minutes later and I pushed it to the side of the road. It finally restarted after five minutes.
I am assuming the tach runs off of the cam sensor because it does not work when the car is running. It move sometimes which cranking.
I am not sure where to go next.
