91 NA Base...no fire to spark plugs

[lgvenable]

I drove my 92 to work yesterday, no issue; but at lunch suddenly there is no fire to the spark plugs, and the car wouldn't start.

It has been running a little rough until it warmed up, then it'd run Ok. Any guesses hwy? I thought blown ECU brain.

Can you tell us more of what you tested to arrive that the plugs aren't firing?

followed troubleshooting guide in the service manual, lead to the ECM. I got in a rebuilt ECM, everything fired right up; no issue with my clifford alarm causing an issue, I did the leaking water pump too, as well as the brake handle micro switch and the windshield wiper switch. Waiting until next ear to do a tt-sl with a Dynamic Racing or Pampena Motorsports stage 3 or 4 TT stroker and then integrate a TT ECU-rebuilt with new electrolytic caps too :<))
