Sometimes bad grounds can cause these problems. Electrical surges are hard on electrical components. I would make sure that the grounds between the engine and frame/ firewall are free of rust and paint.Remove them and sand them to bare metal and add a ground strap here. Think about the fact that your motor sits on rubber mounts and is connected by rubber hoses; this is why grounds are SO important.Did you replace the spark plug wires, cap and rotor? If these are bad along with ground problems, this causes high resistance in your secondary system and electricity takes the easy path to ground and that may mean frying your module. Good luck.

1989 mercury grand marquis battery is fine and so is alternator why won't it start?

First off, does it turn over (crank) and not start? If it does and the motor sounds like it should start and it doesn't then check and see if your car is equipped with an ignition module, which I'm pretty sure it does. If it has an ignition module, replace that and it should solve your problem. Ignition modules are inexpensive and easy to install.

Its on the top of the engine at the right front... coils and ignition module are together. Follow the plug wires, away from the spark plugs, where they will connect into the coil pack.
