Armed with a wiring diagram for your vehicle, it is a simple matter of tracking down an electrical fault in the starting system.

The best place to start is at the starter. Figure 1. Check for power at the "S" terminal of the starter with the key in the START position. If you have power there, then you know the electrical system is good and the problem is with either the starter motor or the starter solenoid. It is always a good idea to replace both as an assembly.

If there is no power there with the key in the START position, then something in the electrical system is bad. The next thing to check is the fuse (1). Figure 2. Determine which is the starter fuse and check that it is good. If not, replace it. If it burns out when you go to start the engine, there is a short circuit in the system. Using your wiring diagram you will need to isolate sections of the starting system to locate the short circuit.

If the fuse is good, the ignition switch is the next place to go. Figure 2. There should be power going into the ignition switch (2). If there is no power there, you have an open circuit in the wiring.
