13 -FUEL > 13A-DIRECT INJECTION AND MULTIPOINT FUEL INJECTION (DI AND MPI) > TROUBLESHOOTING > SYMPTOM PROCEDURES > STARTING IMPOSSIBLE (INITIAL COMBUSTION BUT NO COMPLETE COMBUSTION), IMPROPER STARTING (LONG TIME TO START)
Inspection Procedure 4: Starting Impossible (initial combustion but no complete combustion), Improper Starting (long time to start)
 
 
 
 
COMMENTS ON TROUBLE SYMPTOM
  • Failure is possibly caused by poor ignition, incorrect air-fuel ratio at cranking, improper fuel pressure and so on.
 
 
PROBABLE CAUSES
  • Failed battery
  • Failed ignition system
  • Failed fuel system
  • Failed air-fuel ratio control system
  • Failed intake air system
  • Contamination around the throttle valve
  • Timing chain in out of place
  • Improper compression pressure
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check battery.
  • Check battery (Refer to GROUP 54A - Battery - On-vehicle Service - Battery Test ).
Is the check result normal?
Go to Step 2.
Replace the battery.
 
STEP 2. M.U.T.-IIISE diagnosis code
Is the diagnosis code set?
Inspection chart for diagnosis code (Refer to ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 5: No. 1 intake air temperature sensor
    2. Item 6: Engine coolant temperature sensor
    3. Item 8: Manifold absolute pressure sensor
    4. Item 10: Air flow sensor
    5. Item BB: Barometric pressure sensor
Are the check results normal?
YES : Go to Step 4.
Perform the diagnosis code classified check procedure for the sensor that has shown an abnormal data value. Inspection chart for diagnosis code (Refer to ).
 
STEP 4. M.U.T.-IIISE actuator test
  • Item 2: Fuel pump ON
OK: Operating sound of fuel pump can be heard.
Is the check result normal?
Go to Step 5.
Check Inspection Procedure - fuel pump system (Refer to ).
 
STEP 5. Check air intake from intake hose and inlet manifold.
Is the check result normal?
Go to Step 6.
Repair.
 
STEP 6. Check throttle body (throttle valve portion) contamination.
Is the check result normal?
Go to Step 7.
Clean throttle body (throttle valve portion) (Refer to ).
 
STEP 7. Check injector for operating sound.
  • Check injector for operating sound at engine cranking (Refer to ).
Is operating sound audible?
Go to Step 8.
Check the injector system of the defective cylinder. Check code No. P0261, P0264, P0267, P0270: No. 1, No. 2, No. 3, No. 4 injector circuit low input (Refer to ). Check code No. P0262, P0265, P0268, P0271: No. 1, No. 2, No. 3, No. 4 injector circuit high input (Refer to ).
 
STEP 8. Visual check of ignition spark.
  • Remove the spark plug and install it to the ignition coil.
  • Connect the ignition coil connector.
  • Disconnect all injector connectors.
  • At the engine start, check each spark plug produces a spark.
Is the check result normal?
Go to Step 9.
Check Inspection Procedure - ignition circuit system (Refer to ).
 
STEP 9. Check timing mark on the timing chain.
Is the check result normal?
Go to Step 10.
Align the timing marks.
 
STEP 10. Check compression pressure.
  • Check the compression pressure (Refer to GROUP 11A - On-vehicle Service - Compression Pressure Check ).
Is the check result normal?
Go to Step 11.
Repair.
 
STEP 11. Check injector for spray condition.
  • Check each injector for spray condition (Refer to ).
Is the check result normal?
YES (Engine starting possible) : Go to Step 12.
YES (Engine starting impossible) : Go to Step 13.
Replace the injector.
 
STEP 12. Fuel pressure measurement.
  • Fuel pressure measurement (Refer to ).
Is the check result normal?
Go to Step 13.
Repair.
 
STEP 13. Check for entry foreign matters (water, kerosene, etc.) into fuel.
Is the check result normal?
Go to Step 14.
Replace the fuel.
 
STEP 14. Check the trouble symptom.
Does the trouble symptom persist?
Replace the engine-ECU.
Check end.
