Years back, when your grandparents or older folks would go for long drives, it was common for them to carry a few spare parts. It made sense for them to carry a spare radiator hose set, water, fan belt, wire, a spare set of distributor points and electrical tape, a good spare wheel and hand pump, function jack, etc. Many still do.
With many of our cars now equipped with more modules (aka Ignition Control Modules) than you can count, one part is critical for the post-1974 era GM cars (and US Ford/Mopar). There’s a spare distributor module used in the type of GM engine you have, primarily from 1974 to early 2000’s models.
When a post-1974 to later 1990's era USA General Motors car or light truck suddenly will not start, the car turns over but will not fire, it's most likely the Module in the Distributor. Having a spare HEI (High Energy Ignition) distributor module on hand can be beneficial for several reasons:
-
Preventive Maintenance: The HEI module can wear out over time due to heat and electrical stress. Having a spare allows you to replace it quickly before it fails, ensuring your vehicle remains operational.
-
Simplicity of Replacement: If the module fails while you're on the road, it can be a relatively easy and quick fix compared to other components. A spare allows you to get back on the road without having to wait for a replacement part or a tow.
-
Improve Reliability: Having a spare can enhance the overall reliability of your ignition system, especially for older vehicles where component failure might be more common.
-
Convenience: If you notice signs of module failure (like misfiring, hard starting, or no spark), being able to swap in a spare quickly can save time and hassle.
-
Cost-Effectiveness: If you purchase a spare module in advance, you might save money compared to buying one at the last minute from an auto parts store, especially if you're in a remote location.
-
Racing or Off-Road Use: For those who race or off-road, having a spare can be critical. Conditions in these environments can be harsh, and vehicle reliability is key for performance.
Having a spare HEI distributor module can help mitigate the risk of ignition system failure when you need it most. Please read our site disclaimer and engage the help of a professional before attempting to make any adjustments to your vehicle yourself.
