1. The car doesn’t want to turn over – This may be the most obvious sign that something isn’t right with your ignition coil module. If you’ve tried turning the key multiple times and the car just won’t start, there’s a good chance that the problem is with this component.

2. Remove all of the fuses in this panel, except for the one for the ignition coil module (usually a green fuse).
3. Disconnect the negative battery cable from your car battery.
4. Locate and remove the ignition coilmodule cover (shown here in yellow). There are usually three Phillips head screws holding it in place.)
5. Once removed, you’ll see the ignition coilmodule itself (in blue) and seven wires connected to it (in red, white, black and yellow). The red wire is always attached to +12 volts, while white and black wires are both connected to ground. The other two colors depend on which lead from your battery supplies more voltage
