Electronic Ignition System Components

1996 Saturn SC2 L4-1.9L DOHC VIN 7SECTION Electronic Ignition System Components






MODULE/COIL PACK
The electronic ignition module accepts ignition timing information from the PCM. It charges up the appropriate ignition coil to a preset current limit then turns off the primary current at the desired engine position to create a high voltage signal that is routed to the spark plug to ignite the air/fuel mixture.


SECONDARY WIRES
The secondary wires transmit the high voltage energy from the coil secondaries to the spark plugs.

NOTE: Orientation of the wires to the EI module is critical to the operation of both the module and on-board diagnostics. The orientation is 4 1 2 3 respectively from left to right.


SPARK PLUGS
The spark plugs allow the high voltage energy from the coils to arc across a gap to ignite the air/fuel mixture.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
