Remove the starter motor mounting bolts and remove the starter motor.

The battery cable (the larger cable) and the starter control cable (the smaller cable).

If you encounter a malfunction in the starting circuit, don't immediately assume that the starter is the issue. Begin by checking the battery cable clamps for cleanliness and tightness at the battery connection. Inspect the battery cables and replace any defective ones. Test the battery's condition, and if it fails, replace it. Check the starter solenoid wiring and connections using wiring diagrams. Verify the tightness of the starter mounting bolts. Ensure that the shift lever is in PARK or NEUTRAL (automatic transaxle) or the clutch pedal is pressed (manual transaxle). For vehicles with automatic transaxle, check the adjustment of the Transmission Range (TR) switch, and for manual transaxle, ensure the clutch start switch is correctly installed. If the starter motor doesn't operate when the ignition switch is turned to START, check for voltage to the solenoid using a test light or voltmeter while an assistant turns the ignition switch to START. If voltage is absent, inspect the starting system circuit using wiring diagrams. If voltage is present but the starter doesn't work, remove it from the engine compartment and bench test it. If the starter turns over slowly, perform a starter cranking voltage and current draw test with the starter assembly on the engine. Observe battery voltage and current draw using an amp meter, making sure they stay within the correct range. If not, replace the starter with a new unit. To check the starter/solenoid assembly on the bench, connect jumper cables, apply battery voltage to the solenoid, and observe the movements of the solenoid plunger, shift lever, and pinion drive. Depending on the observations, identify whether the solenoid, starter motor, or starter/solenoid assembly is defective.

Turn the ignition key to OFF, then disconnect the cable from the negative battery terminal. Raise the front of the vehicle and place it securely on jackstands. On 2.0L Supercharged models only, drain the intercooler coolant system and remove the intercooler system electric water pump. Disconnect the battery cable (the larger cable) and the starter control cable (the smaller cable) from the starter solenoid terminals. Remove the starter mounting bolts and remove the starter. On 2007 and later models, you may have to remove the Secondary Air Injection pump to allow room for starter removal. Installation is the reverse of removal. Tighten the starter mounting bolts. When the battery has been disconnected, the PCM must relearn its former driveability and performance characteristics.

For four-cylinder models, start by turning the ignition key to OFF and disconnecting the cable from the negative battery terminal. Then, raise the front of the vehicle and secure it on jackstands. Disconnect the battery cable and the starter control cable from the starter motor solenoid terminals. Remove the starter motor mounting bolts and take out the starter motor. To reinstall, follow the reverse steps and tighten the mounting bolts to the specified torque. For V6 models, begin by turning the ignition key to OFF and disconnecting the cable from the negative battery terminal. Loosen the right front wheel lug nuts and raise the front of the vehicle on jackstands. Remove the right front wheel and disconnect the battery cable and starter control cable from the starter motor solenoid terminals. Detach the wiring harness clip from the engine block and push it aside to access the starter motor. Remove the lower starter motor mounting bolt and lower the vehicle. Then, remove the upper starter motor mounting bolt and take out the starter from the engine. To reinstall, follow the reverse steps and tighten the mounting bolts to the specified torque.

If the starter fails to engage when turning the ignition switch to the start position, you should assess the voltage at the starter solenoid's "S" terminal, comparing it to battery voltage, and consult wiring diagrams to check starting system fuses and the starter relay.

Raise the vehicle and support it securely on jackstands.

The upper mounting bolt should be removed using a socket and extension.

The transmission should be confirmed to be in the correct position (PARK or NEUTRAL for automatic transaxles or clutch pedal pressed for manual transaxles).
