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

Before using this chart, ensure battery condition, engine cranking speed and fuel quality have been checked.

When ignition is turned to ON or START position, main relay applies battery voltage to ignition coil. If ignition coil's primary coil is being toggled to ground through ignitor, sending a signal to ECM, a high voltage is induced in secondary windings of ignition coil and is applied through distributor to spark plugs.

1. Checks for any trouble codes stored in ECM memory.
2. Checks for spark at ignition coil.
3. Checks for spark at distributor.
4. Checks for spark at spark plugs.
