Before troubleshooting the ignition system, check the following:
1. Make sure that electrical harness and ignition switch are not the source of the problem.
2. Check that plug-in connectors are fully engaged and terminals are free of corrosion.
3. Make sure that wire connections are tight and free of corrosion.
4. Check all electrical components, that are grounded directly to engine, and all ground
wires to see that they are grounded to engine.
5. Check for disconnected wires and short and open circuits
