Engine Cranks But Will Not Start

1. Check fuel tank contents and fuel gauge accuracy. Check for dirt, water or contamination in fuel.
2. Check fuel lines and fittings for leaks. If no leaks are found, check fuel delivery system for proper pressure and volumes. Reset Inertia Fuel Shutoff (IFS) switch (if necessary).
3. Check for damaged or contaminated fuel injector wiring harness and connector. Ensure fuel injectors pulse when engine is cranked.
4. Check ignition system for strong spark at spark plugs. If spark is not present or if spark is weak, proceed as follows:
   • On all EEC-V models, go to TEST JE in appropriate SELF-DIAGNOSTICS article.
   • On all others, go to appropriate SELF-DIAGNOSTICS article.
5. Check engine compression.
6. Check valve timing.
7. Check for overheating engine.
8. Check for intake air system leak.
9. Check operation of Idle Air Control (IAC) valve.
10. Check for damaged or faulty crankshaft pulley and Crankshaft Position (CKP) sensor.

Repair as necessary.
