Since there is no spark (watch the tach when you try and start it. does it move at all?) that points to either the hall effect sensor on the distributor or the power stage unit. I've got a 89 760 with the same problem, and narrowed it down to the power stage (thanks mcduck) by checking on pin 5 on the harness going to the power stage. Look for a pulsing 5 volts when the motor is turning over. Mine also shows a ground on pin 1, but i'm not sure if that's correct. I need to get a really good look @ the harness to see which wire goes where. Anyone have any good wiring diagrams for the ignition of these parts?
