bad ecm
 

Yes folks i have a bad ECM car is drivable of course just it won't go into diagnostics mode so i don't know what is wrong with the car (well there is no light so nothing is{backfire backfire stall** :confused: ) is there anybody that knows where i can get a 93 T/A's ECM from for cheap and working condition?

Check around at a junk yard, problem is that 93's have a different type of transmission so a PCM only from a 93 F-Body car will work.

make sure it's a gm with updates 90% of the aftermarket ones are reman old programing that may (read more than likely will) go bad, or as with the '95 f body need the update that was part of a tsb for cold start issues
