Ok...so I was throwing code 9 (cyp sensor)...because my rotor screw came loose and all hell broke out. I just replaced the distributor housing, rotor, cap, leak cover, except the ICM (igniter unit).
Fired up the car...ran fine for 5-10mins as I set the timing. Shut car off.

Come back...turn on the car...notice my tach bounce up and down from 1-3rpm rapidly...but then seems fine...after driving for 3 mins...car dies. Turns on...then dies...now won't start up.

Do you think it's the igniter?

Had a very similar problem, my tach bounced and died. It turned out to be the ICM. I guess the only way to be sure is to maybe try a friends(if one is available) or test voltage and compare to what the HELMS says. Good luck
