Test NS-2: Checking Engine Mechanical Systems
- Attempt to start engine. If engine does not start and remain running, go to next step. If engine starts and remains running, test is complete.
- Check for proper spark plug wire routing and firing order. Firing order is 1-2-3-4-5-6. Cylinder No. 1 is front cylinder on right side when viewed from flywheel end of engine. Cylinder No. 2 is front cylinder on left side when viewed from flywheel end of engine. Cylinders No. 1, 3 and 5 are on right side of engine and cylinders No. 2, 4 and 6 are on left side of engine. If spark plug wires are correct, go to next step. If spark plug wires are incorrect, repair as necessary. Perform TEST VER-1A
.
- Remove all spark plugs. Inspect sparks plugs for wetness caused by fuel. If spark plugs are not wet, go to next step. If spark plugs are wet, clean spark plugs. Perform TEST VER-1A
.
- Check compression on all cylinders. If compression on all cylinders is at least 100 psi (7 kg/cm2
) and compression between all cylinders is within 25 percent of each other, go to next step. If compression on all cylinders is not at least 100 psi (7 kg/cm2
) and compression between all cylinders is not within 25 percent of each other, repair engine mechanical problem as necessary. Perform TEST VER-1A
.
- Following additional items should be checked as possible causes:
- Check for related Technical Service Bulletins (TSBs) for a no start condition.
- Check engine valve timing for proper timing belt installation.
- Check exhaust system for restrictions.
- Ensure PCV system is functioning properly.
- Check secondary ignition system.
- Check for contaminated fuel.
