yes, it can happen. check for spark from the number one coil using spark plug wire and hold it near a grounded point. it should be a consistent spark with engine running. compare to different coil wire for verification. those coil packs are partially replace able because each coil fires two plugs. replace the no.1 portion with a new one from parts store. 28.00

The answer to that question is TOTALLY different depending on which engine your Gran Prix is equipped with. The choices are:
> V6-3.8L VIN 2
> V8-5.3L VIN C
> V6-3.8L SC VIN 4
This is really must know information - especially if you are asking somebody for help with your engine, engine accessories, or engine control systems.

you only need to change this if it stops working or one set of the coils stops or causes a firing problem.also keep in mind that if a complete coil stops working it could be the ignition module causing the problem

I assume you mean the ignition keyswitch. You'll have 12 Volt ignition power from the IGN fuse or fusible link. There will also be an ignition terminal and a starter solenoid terminal. If you have the GM key security system (with the little black and silver resistor embedded in the ignition key), there will be two more wires going to the engine computer for checking the resistor.
I don't have the wire identification for these, except an educated guess that the power and solenoid wires will probably be the largest ones, and the power wire is most likely red. The solenoid and ignition wires probably have different colored stripes on the insulation. The anti-theft key wires are functionally interchangeable, although they may share a one-way connector that plugs into the switch (they are probably also the smallest wires since they don't need to carry a lot of current).
