Question about 1998 Pontiac Grand Prix
To check the coilpack just get a test light ground it some where on
the block then press the the test light on the head of each wire at the
coilpack. You should hear a change in the way the car idles, if you get
to one of the wires and the idle does not change, that is the cylinder
that is giving you the problem; but it could be dead cylinder and not
the coil pack.
In other words...
1. Set the dial on your voltmeter to "Ohms."
2. Touch one of the leads on the voltmeter to one of the electrical terminals on the coil pack. There are two terminals: one on the top of the coil pack and one on the bottom. It does not matter which lead from the voltmeter touches which terminal on the coil pack. Then, touch the other lead on the voltmeter to the other terminal on the coil pack.
3. Check the resistance. The display on the voltmeter should read between "0.0" and "0.05" Ohms. If it reads higher than "0.05" Ohms, then you need to replace the coil pack.
Hope helps (remember rated this).

the coils are one integrated block with 3 separate segments. the coil pack is mounted to the ignition module and can be unbolted from each other. one can test the coils from the underside of the coilpack with a dvom. having said that your car should still start if one paired coil fails, it would however miss on one or two cylinders. I would suggest to scan for codes, monitor live sensor data to see if you have a valid crank signal, check fuel pressure and spark voltage

SOURCE: No spark from coil pack
The most common reasons for them going out are not using dielectric
grease properly when installing, and from washing your engine.
I believe this was a huge issue with Volkswagen vehicles
