How to Replace the Ignition on a 1999 Pontiac Grand Prix

The 1999 Pontiac Grand Prix (available as a two-door coupe or a four-door sedan) typically has a six-cylinder 3.8-liter engine. The purpose of the ignition module is to control the electrical current to the spark plugs. The ignition module in the 1999 Pontiac Grand Prix is on top of the engine. The procedure for replacing the ignition module is similar for all Pontiac Grand Prix models with a 3.8-liter engine made from 1997 to 2000.

Instructions

1

Disconnect the cable for the negative battery terminal with a socket wrench. This will reduce the risk of electrocution while replacing the ignition assembly.

2

Label the wires to the spark plugs with tape to facilitate the installation of the new ignition module. You must reconnect the spark plug wires to their correct locations on the ignition assembly. Disconnect the spark plug wires from the ignition coils.

3

Remove the mounting screws for the ignition coils with a socket wrench and disconnect the ignition coils from the ignition module. Remove the fasteners for the ignition module and disconnect it from the engine.

4

Install the ignition coils to the new ignition module and fasten the retaining screws for the ignition coil. Torque the retaining screws to 40 inch-lbs. with a torque wrench.

5

Connect the spark plug wires to the ignition coils according to the labels you made in step 2. Attach the cable to the negative battery terminal with a socket wrench.
