    It goes without saying but I'm gonna' say it anyway that when the ignition module ICM goes bad, your car, or minivan, or Isuzu SUV will not start, but not always. Every now and then, this type of ignition module fails intermittently. What this means is that the vehicle will start and run most of the time, but now and then it won't.

    If you're experiencing this, you'll have to test the ignition module when the vehicle is not wanting to start. This is important, because as long as it starts, the problem does not exist and can not be tested.

    In the Lumina, the ignition switch is mounted low on the steering column and actuated by a gear and rod mechanism attached to the end of the key lock cylinder. The heavy duty contacts in the ignition switch control the supply of electrical energy to the starting, charging and accessory systems in the car.

The solenoid acts like a switch, opening and closing the high amperage circuit to the starter. The ignition key supplies the power to actuate a relay, which in turn actuates the solenoid. Disconnect the battery terminals, using a wrench.

    Mount the starter relay. The relay should be mounted in the fuse relay box or close to the fuse relay box. If it fits in the box, the wires can be inserted through the back.

    If it does not fit, then it should be mounted on the fender well as close to the battery as possible. Connect the inline fuse to the battery positive terminal by using the gauge wire and installing a yellow circular post connector on the end of the wire. Crimp it with the crimping tool. Install this terminal under the bolt on the positive terminal. Unroll the wire and run it to the starter relay.

    Conceal the wire wherever possible up to the relay. Install a yellow female spade terminal on the end of the wire, then crimp it. Run another piece of gauge wire from the relay to the starter solenoid. Crimp a yellow spade terminal on the relay end of the wire and install it on the "S" terminal on the relay. Install the appropriate wire terminal on the solenoid end and install it on the small "I" terminal on the solenoid.

    Run another piece of wire from the "G," or ground, terminal on the relay to a good ground on the body. Use a yellow spade terminal for the relay and a yellow post terminal on the ground end of the wire. Install the starter wire from the ignition switch to the "I" terminal on the relay, which is the last remaining open terminal.

    To identify the starter wire on the ignition switch, just look for the "S" terminal.Chevrolet Silverado Repair Manual. Maintenance Schedule for your Chevrolet Silverado.
