Repair Procedure - A

REPAIR PROCEDURE "A"

1. Verify concern by attempting to start engine.

- If engine starts, return vehicle to customer.

- If engine fails to start, go to STEP 2.

2. Disconnect the secondary air injection pump electrical connector (B1-04).





NOTE:
This will protect the catalytic converter by preventing rapid light off due to unburned fuel purging from the engine in the following steps.

CAUTION:
The following steps will force un-burnt fuel from the combustion chambers through the spark plug holes. Use caution not to create sparks or other sources of ignition during these steps. Perform this procedure in a well ventilated area.

3. Remove all 4 spark plugs from the engine. See workshop manual section 01-18 SPARK PLUG REMOVAL/INSTALLATION.





4. Disconnect Eccentric Shaft Position Sensor (ESPS) B1-27 connector.

NOTE:
This will cut fuel injection and spark while performing the procedure.

5. Place cloth near spark plug holes to absorb fuel residue.

6. Crank the engine until all fuel is purged from spark plug holes. (Do not crank engine longer than 10 seconds. If more than 10 seconds is required, wait 5 seconds in between cranking.) Perform this procedure in a well ventilated area.

7. Connect ESPS connector B1-27.

8. Install new spark plugs.

9. Attempt to start engine without depressing accelerator pedal.

- If the engine starts, go to STEP 10.

- If engine fails to start, the engine compression may be lower than specification. Go to REPAIR PROCEDURE "B".

10. Keep engine running between 1500-2000 RPM until engine speed has stabilized. Maintain this engine speed until all smoke has dissipated and / or engine has come to full operating temperature.

NOTE:
Do not race the engine, this may cause catalyst damage.

11. Shut engine off.

12. Connect the secondary air injection pump connector B1-04.

13. Erase all DTCs and confirm repairs.
