i have a 94 z28 with the 4l60e trans. i recently put a 95 motor out of a trans am in my camaro. but no spark at the plugs. i have spark at the coil and the opti is said and looks to be brand new. any helping ideas?

 

What did you do about the difference in the opti harness connectors? Are you using the 94s engine harness or one that came with the 95?
