I just tried transplanting my 8746 with a custom chip into my 1988 sport coupe with a 350 and the car won't start - it just turns over and over and over and....u get the idea. Is there anything one could overlook? I just replaced the 8746 chip with my new one and plugged it in - i'm figuring it should work. Any help would be great - thanks again.

Did you check the pinouts? How about the stock chip?

the pinouts? if those are the metal pins in the computer that the harness plugs into - its fine. And i wasn't sure to try the stock chip in the computer b/c the only chip i have left is for the OLD computer which isn't a 8746, its a 8036 or something. Argh

If VATS is enabled in the 8746 PROM you will have a no start condition.

 

so with the vats the car will just crank over but won't fire/start correct? So if its disabled then my car should run???? What is vats anyway?

Correct

Correct, if that is the only problem.

What is vats anyway?

An anti theft system. A quick search of this board for "VATS" will get you the specifics. The FAQ off the main page contains some info too.
