1 | Did you perform the Engine Electrical Diagnostic System Check? | Go to Step 2 | Go to Diagnostic System Check - Engine Electrical
2 | Turn the ignition to the Start position. Is the Theft indicator flashing? | Go to Diagnostic System Check - Theft Deterrent in Theft Deterrent | Go to Step 3
3 | Turn the ignition to the Start position. Does the starter solenoid click? | Go to Starter Solenoid Clicks, Engine Does Not Crank | Go to Step 4
4 | Does the vehicle have an automatic transmission? | Go to Step 5 | Go to Step 7

1. Disconnect the transmission range switch.
2. Connect a test lamp between the crank voltage circuit of the transmission range switch harness connector and ground.
3. Turn the ignition to the Start position.

Does the test lamp illuminate?

Important: You must use 10 AWG wire for the fused jumper. Any smaller wire will cause too high of resistance and a misdiagnosis will occur.

1. Connect a 15 A fused jumper wire between the crank voltage circuit of the transmission range switch and the starter solenoid crank voltage circuit of the transmission range switch.
2. Turn the ignition to the Start position.

Does the engine Crank?

Important: Place the transmission in neutral and set the parking brake.

1. Disconnect the Clutch Pedal Position (CCP) switch.
2. Connect a test lamp between the crank voltage circuit of the CCP switch harness connector and ground.
3. Turn the ignition to the Start position.

Does the test lamp illuminate?

Go to Step 13

Go to Step 10

9 | Test the crank voltage circuit of the transmission range switch or CCP 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 19 | Go to Step 11
10 | Test the starter solenoid crank voltage circuit for a short, 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 19 | Go to Step 14
11 | Inspect for poor connections at the ignition switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 15
12 | Inspect for poor connections at the transmission range switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 16
13 | Inspect for poor connections at the CCP switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 17
14 | Inspect for poor connections at the starter solenoid. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 18
15 | Replace the Ignition Switch. Refer to Ignition and Start Switch Replacement in Steering Wheel and Column. Did you complete the replacement? | Go to Step 19 | --
16 | Replace the transmission range switch. Refer to Park/Neutral Position Switch Replacement in Automatic Transaxle - 4T40-E/4T45-E. Did you complete the replacement? | Go to Step 19 | --
17 | Replace the CCP switch. Refer to Clutch Pedal Position Switch Replacement in Clutch. Did you complete the replacement? | Go to Step 19 | --
18 | Replace the Starter Motor. Refer to Starter Motor Replacement . Did you complete the replacement? | Go to Step 19 | --
19 | Operate the system for which the symptom occurred. Is the symptom still present? | Go to Step 2 | System OK
