Did you perform the Diagnostic System Check for Engine Electrical?

Go to Step 2

Go to Diagnostic System Check - Engine Electrical

Turn the ignition to the START position.

Does the starter solenoid click?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

1. Turn OFF the ignition.
2. Disconnect the starter solenoid crank voltage circuit from the starter solenoid.
3. Connect a test lamp between the starter solenoid crank voltage circuit of the starter solenoid and a good ground.
4. Turn the ignition to the START position.

Does the test lamp illuminate?

Go to Step 7

Go to Step 4

1. Turn OFF the ignition.
2. Disconnect the Park/Neutral Position (PNP) switch.
3. Connect a 10 Amp fused jumper between the crank voltage circuit of the PNP switch and the starter solenoid crank voltage circuit of the PNP switch.
4. Turn the ignition to the START position.

Does the test lamp illuminate?

Go to Step 8

Go to Step 5

1. Connect a test lamp between the crank voltage circuit of the PNP and a good ground.
2. Turn the ignition to the START position.

Does the test lamp illuminate?

Go to Step 11

Go to Step 6

Test the crank voltage circuit of the PNP switch for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 15

Go to Step 10

Inspect for poor connection at starter solenoid. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
