1G-4 IGNITION SYSTEM
Intermittent failure is temporary. The engine may
refuse to start on the first try, but will eventually start.
If an intermittent failure occurs when the engine is
running, it may falter but will continue to run. If it
stalls, it will re-start and will continue to run.
The primary system consists of:
• Battery feed to ignition coil.
• Ignition coil primary winding.
• All wires connected to electronic control unit.
• Distributor
S p a r k knock is not a failure mode. The engine will
start and will continue to run. If not corrected, spark
knock can do extensive damage to internal engine
components.
Ful! Failure Diagnosis
The first step in diagnosing a failure is to identify
which system—primary or secondary—is faulty.
The secondary system consists of:
• Ignition coil secondary winding.
• All heavy wires installed in distributor cap.
• Distributor cap.
• Distributor rotor.
• Spark plugs.
