- Check fuel tank contents and fuel gauge accuracy. Check for dirt, water or other contamination in fuel.
- Check ignition system for strong secondary current at spark plugs. If no spark exists or if spark is weak, repair ignition system problem.
- Check fuel lines and fittings for leaks. If no leaks are found, check fuel delivery system for proper pressure and volumes. Reset inertia switch (if necessary).
- Check for a defective fuel injector or coolant temperature sensor. Ensure TPS does not stick. ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
