Checking The Fuel Injection System, Ignition System And Components

NOTE:

In the event of diagnostic trouble codes (DTCs), that affect camshaft control or camshaft reset valve, these must be fault-traced first.

HINT: In certain cases, the engine control module (ECM) can determine which cylinder has misfired.

Check the fuel level in the fuel tank.

Check that the engine oil level is correct.

Look for moisture in the electrical terminals for the ignition coils and in the spark plug wells.

Check the spark plugs. Search for damage in the insulation and other damage.

Check the engine intake system for leakage.

Check the crankcase ventilation. Check for blockage.

Check the fuel pressure and residual pressure.

Check the compression of the engine.

Remedy as necessary.
