Here is a engine wiring diagram (4 and 6 cyl) and if at all possible have a scan done, it may help pin point the problem.

Hello it's me once again I had an car electrician come to my home today and I watched him go through a strenuous wire by wire work out and every wire was perfect I even replaced the coils module and crank sensor again just to be sure and still no spark wow I'm truly burnt out some one said to check the timing chain and the rings behind the harmonic balancer that they maybe they could be out of alignment heeeeeellllllpppppp

Hi Gary, I know this is a long time after you a sked your question, but did you ever get your problem figured out? I also have a 1989 Cutlass Ciera. Question: Did the no spark to the plugs just come out of the blue, or did you or someone else do something to the car , work on it etc. beforehand ? Where you plug the coils into, I can't remember what that's called but that alone can go bad.
