Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

Turn the ignition to the Start position.

Is the theft indicator flashing?

Go to Diagnostic Trouble Code (DTC) List - Vehicle

Go to Step 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

Does the vehicle have an automatic transmission?

Go to Step 5

Go to Step 8

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Place the transmission in Park or Neutral.
4. With a scan tool, observe the TR Sw. or Transmission Range parameter in the transmission data of the engine control module (ECM)/powertrain control module (PCM) data list.

Does the scan tool display Park or Neutral?

Go to Step 6

Go to Range Selector Displays Incorrect Range

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?

Go to Step 7

Go to Step 10

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

1. Connect a 15-amp 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?

Go to Step 13

Go to Step 11

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 9

Go to Step 10

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

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

Does the engine crank?

Go to Step 14

Go to Step 11

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 .

Did you find and correct the condition?

Go to Step 16

Inspect for poor connections at the transmission range switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .

Did you find and correct the condition?

Go to Step 20

Go to Step 17

Inspect for poor connections at the CCP switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .

Did you find and correct the condition?

Go to Step 20

Go to Step 18

Inspect for poor connections at the starter solenoid. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .

Did you find and correct the condition?

Go to Step 20

Go to Step 19

Replace the ignition switch. Refer to Ignition and Start Switch Replacement .

Did you complete the replacement?

Go to Step 20
