Answer
Hi Jim:
Did your timing chain break or come off? I think your Caddy just jumped timing. When you are cracking her, is there any indication that she is trying to start? If so, check the distributor. My guess is your timing is off or way off. The timing of the cylinders are out of sync with the plugs spark, which is control by the distributor. Do you have the timing sequence for you car? You will need this to fix the problem.
