no spark spark plugs
91 Bonneville... The engine is turning, having no problem turning at that. It just won't fire up. We pulled out one of the spark plugs and there is no spark.
What do I do?
Any help?

You have the old single module/coil pack setup. That can likely be the failure. It is possible for you to swap to the newer style ICm and coils.

I believe the coil pack isn't the problem here.... we put another one on from a newer car and it changed nothing...
Do you know if the computer is totally blown, would the engine still at least turn over?

Doesn't the cam or crank sensor play a role in whether the coils fire up or not?
