I got a 1990 with a 5.8 distributor was already out when stabing the new distributor #1 is at TFC ON COMPRESSION STROKE without a doubt. The harmonic balancer looks good pointer is pointed to 0 degrees pulled spout connector set base timing to 10 degrees BTC plug spout back in will not start. Tested coil no spark replaced coil tested ignition modual and PIP all good. It will start with the base timing set to 10 degrees BTC but dies within mins as if it was shut off by the key. Any help appreciated.
