Engine Cranks But Will Not Start

  1. Check fuel tank contents and fuel gauge accuracy. Check for dirt, water or other contamination in fuel.
  2. Check ignition system for strong secondary current at spark plugs. If no spark exists or if spark is weak, repair ignition system problem.
  3. 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).
  4. Check for a defective fuel injector or coolant temperature sensor. Ensure TPS does not stick.
WARNING: Always relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
