Okay gentleman, here is the situation. I was driving and my car just sputtered and cut off. It started right back up but after sitting for an hour or so it will not start. During cranking I saw some flames shoot from the tbi unit. If I hold the gas pedal down it will start but die right off. My question is, will a bad ignition module cause this? I was able to pull codes and got code 43 (ESC unit failure). I tested the pick-up coil and it checked out fine. The only thing that I did not do was test for spark. Go figure. Any ideas?

 

What would cause the Electronic Spark Control Module to go bad? I have been doing research but cant find anything. The only thing that was done out of the ordinary was I left the key in the "run" position for like 10 minutes while I scanned the ECM. Any ideas? I dont want to spend $145 and that is not the issue.

 

most autoparts stores allow you to check ur ign module for free. so thats a good place to start that way u can be sure its either good or bad.

 

bad icm can be caused by bad pickup coils over heating getting wet symtoms are bad idleing no ideling missin no spark if you take off the icm turn it over look at the botton you will see like alil burn mark doing this you will need new termal grease if you reinstall
