Hello my firebird is not getting fire from the coil I have replaced coil and the complete distributor I'm wondering if my next thing is going to be the computer?

 

I would suspect the wiring if replacing the dizzy didn't do it, wiring and the pickup coil(part of the dizzy) would be the two most likely suspects, so before throwing more parts at it, I would check all ignition wiring over. Also could be the ICM if new dizzy didn't come with one.

 

I'm going to look at the wiring I've replaced every thing the ICM the computer pickup coil cap rotor every thing! I also have 12 V power making it all the way to the ICM. but thank you for the comment I'm willing to try anything at this point.

 

If someone used a quick crimp connect for a tach, they will cut the wires over time and you won't notice it.
