Step	Action	Yes	No
Schematic Reference: Starting and Charging Schematics
1	Did you perform the Diagnostic System Check for Engine Electrical?	Go to Step 2	Go to Diagnostic System Check - Engine Electrical
2	Turn the ignition switch to the START position. Does the engine crank?	Go to TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS in Wiring Systems	Go to Step 3
3	Is the security indicator flashing?	Go to DIAGNOSTIC SYSTEM CHECK-THEFT DETERRENT in Theft Deterrent	Go to Step 4
4	Install a scan tool. Turn ON the ignition, with the engine OFF. With a scan tool, observe the Crank request signal parameter in the PCM data list. Turn the ignition switch to the START position. Does the scan tool display Yes?	Go to Step 5	Go to Step 13
5	Turn ON the ignition, with the engine OFF. With a scan tool, observe the Starter Relay Command parameter in the PCM data list. Turn the ignition switch to the START position. Does the scan tool display Yes?	Go to Step 7	Go to Step 6
6	Turn ON the ignition, with the engine OFF. With a scan tool, observe the Current Gear or TR Sw. (Trans Range Switch) parameter in the PCM data list. Verify that the transmission is in Park or Neutral. Does the scan tool display Park or Neutral?	Go to Step 7	Go to RANGE SELECTOR DISPLAY INOPERATIVE OR DISPLAY
7	Turn the ignition switch to the START position. Do you hear the STARTER relay click?	Go to Step 10	Go to Step 8
8	Turn OFF the ignition. Disconnect the STARTER relay. Turn ON the ignition, with the engine OFF. Connect a test lamp between the battery positive voltage circuit of the STARTER relay coil and a good ground. Does the test lamp illuminate?	Go to Step 9	Go to Step 21
9	Connect a test lamp between the battery positive voltage circuit of the STARTER relay coil and the control circuit of the STARTER relay. Turn the ignition to the START position. Does the test lamp illuminate?	Go to Step 17	Go to Step 15
10	Turn OFF the ignition. Disconnect the STARTER relay. Connect a test lamp between the battery positive voltage circuit of the STARTER relay switch and a good ground. Does the test lamp illuminate?	Go to Step 11	Go to Step 22
11	Connect a 30 amp fused jumper between the battery positive voltage circuit of the STARTER relay switch and the starter solenoid crank voltage circuit. Does the engine crank?	Go to Step 17	Go to Step 12
12	Does the fuse in the jumper open?	Go to Step 23	Go to Step 14
13	Turn OFF the ignition. Disconnect the PCM harness connector. Connect a test lamp between the crank voltage circuit of the PCM and a good ground. Turn the ignition to the START position. Does the test lamp illuminate?	Go to Step 20	Go to Step 16
14	Test the starter solenoid crank voltage circuit for a high resistance or open. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems. Did you find and correct the condition?	Go to Step 28	Go to Step 18
15	Test the control circuit of the STARTER relay for an open or short to battery voltage. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems. Did you find and correct the condition?	Go to Step 28	Go to Step 20
16	Test the crank voltage circuit of the PCM for a high resistance or open. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems. Did you find and correct the condition.	Go to Step 28	Go to Step 19
17	Inspect for poor connections at the STARTER relay. 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 28	Go to Step 24
18	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 28	Go to Step 25
19	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 28	Go to Step 26
20	Inspect for poor connections at the harness connector of the PCM. 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 28	Go to Step 27
21	Repair an open or high resistance in the battery positive voltage circuit of the STARTER relay coil. Refer to WIRING REPAIRS in Wiring Systems. Did you complete the repair?	Go to Step 28	-
22	Repair the open or high resistance in the battery positive voltage circuit of the STARTER relay switch. Refer to WIRING REPAIRS in Wiring Systems. Did you complete the repair?	Go to Step 28	-
23	Repair the short to ground in the starter solenoid crank voltage circuit. Refer to WIRING REPAIRS in Wiring Systems. Did you complete the repair?	Go to Step 28	-
24	Replace the STARTER relay. Refer to RELAY REPLACEMENT (WITHIN AN ELECTRICAL CENTER) or RELAY REPLACEMENT (ATTACHED TO WIRE HARNESS) RELAY REPLACEMENT in Wiring Systems. Did you complete the replacement?	Go to Step 28	-
25	Replace the Starter Motor. Refer to Starter Motor Replacement (4.2L Engine) . Did you complete the replacement?	Go to Step 28	-
26	Replace the ignition switch. Refer to IGNITION SWITCH in Steering Wheel and Column. Did you complete the replacement?	Go to Step 28	-
