The miserable beast now won't start at all. No spark (confirmed at plugs). Wires, plugs, cap, rotor, coil all work. The problem seemed to be time/heat related. Whatever caused the ignition to die after 5 min but allowed a restart 5 min later has now died. It won't start at all.
I have tried 3 powerstages from cars that were running. I put a good layer of thermal compound between the stage & heatsink.
No oil inside dist cap. I pulled the distributer & the hall sensor wires & connector are good. There is 12 VDC at the powerstage & all resistances/voltages are as listed in FAQ.
I have tried 2 ignition computers, I even tried 2 different ECU's & AMM's (getting desperate).
After I pulled the distributer I rotated it by hand & checked voltage from ground to pin 24 of the ignition computer. The power is disconnected to the coil for this test. The voltage went from 5 VDC to 0 VDC & back to 5 VDC just like it should. Every time the sensor triggered there was a short pulse sent to the injectors (dble checked w/ a noid light).
The tests I have done are the ones for EZ117 ignitions in the FAQ.
The only odd thing is that when cranking the engine the tach doesn't move at all. This is supposed to be the quick way of testing the Hall sensor. The tach needle jumps slightly when the key is first turned to ignition on. The needle doesn't move again.
I'm going to get a distributer from the wrecker tomorrow then if it doesn't work the SOB is going to a garage before I set it on fire.
