Chart A-3, Engine Cranks But Will Not Run: Notes

Before using this chart, battery condition, engine cranking speed and fuel quantity should be checked and verified as being okay.

When ignition switch is in ON or START position, battery voltage is applied to ignition coil. If ignition coil's primary coil is being toggled to ground by the ECM, a high voltage is induced in the secondary windings of ignition coil and is applied through the distributor to the spark plugs.

NOTE: Test numbers refer to test numbers on diagnostic chart.
  1. Checks to see if any diagnostic trouble codes are stored in ECM's memory.
  2. Checks for spark at ignition coil.
  3. Checks for spark at distributor.
  4. Checks for spark at spark plugs.
