1979 Jeep CJ-5 Common Ignition Problems
A faulty ignition control module can indeed lead to sudden stalls or cranking without starting in a 1979 Jeep CJ-5. However, it's worth noting that several components work together in the Jeep's ignition system, and issues with any of them can cause similar symptoms.
Here are some common ignition-related problems in the 1979 CJ-5:
1. Spark Plugs and Distributor Cap: Worn-out spark plugs or a cracked distributor cap can cause ignition issues. Inspect and replace them if necessary.
2. Ignition Coil: A faulty ignition coil may not provide enough voltage to the spark plugs, leading to starting or stalling problems.
3. Fuel System: A clogged fuel filter, a faulty fuel pump, or issues with the fuel lines can affect the fuel supply and result in engine stalls or rough running.
4. Wires and Connections: Loose or damaged electrical wires and connectors in the ignition system can disrupt the signal between components, leading to intermittent stalling.
5. Ground: Poor grounding can also cause various electrical problems, including stalling. Make sure the ground wires are properly connected and clean.
If you have tried replacing the ignition control module and still encounter the same problem, it would be best to have a professional mechanic inspect the entire ignition system and determine the root cause of the issue.
