The ignition control module and ignition coils in your 2000 Chevrolet Monte Carlo work as a single unit to control the voltage and the timing of the spark delivered to each of the pistons in the engine block. However, you can remove the coils to replace a failed ignition module without having to replace the whole assembly. Better yet, you can install the new ignition module in your garage with a few common tools right out of your toolbox in about an hour or less.

[edit] Install Ignition Module

Remove the Ignition Module

  • Open the hood of your Monte Carlo. Follow the spark plug wires coming out of the engine towards the other end where they connect with the ignition coils. The ignition coils mount on the ignition module.
  • Number each spark plug wire and ignition coil with a piece of masking tape and a black marker so that you reinstall each wire and coil in its corresponding place on the new ignition module during the reassembly process.
  • Grab each spark plug wire by the boot that connects to the ignition coil and pull it off carefully with a twisting motion.
  • Unfasten the two bolts holding each of the three ignition coils to the ignition module using a ratchet, short ratchet extension and socket.
  • Unplug the electrical connector from the ignition module. If you have a 3.8L engine model, unfasten the bolt holding the electrical connector to the ignition module first, using a ratchet and socket, before attempting to unplug it.
  • Unfasten the ignition module from the mounting bracket using a ratchet, short ratchet extension and socket. Remove the module from the vehicle.

Install the New Ignition Module

  • Place the new ignition module in position on the mounting bracket and install the mounting bolts finger tight. Tighten the bolts with the ratchet, short ratchet extension and socket.
  • Plug in the ignition module electrical connector. If you have a 3.8L engine model, fasten the bolt to secure the electrical connector to the ignition module, using the ratchet and socket, after plugging in the connector.
  • Replace the three ignition coils and tighten the mounting bolts with the ratchet, short ratchet extension and socket.
  • Connect the spark plug wires to the ignition coils. Make sure each spark plug wire snaps in place over the tower connectors on the ignition coils.
  • Close the hood.
