Secondary Ignition
for your 1990 GMC C2500


Your GMC C2500 ignition system includes two circuits that work together to deliver the spark to the spark plug. The secondary ignition connects the spark plug and ignition coil, while the primary circuit connects the coil and battery. Malfunctions in either circuit can cause problems starting your vehicle, so consider replacement parts from StockWiseAuto.com.


In today's vehicles, you have a choice of either an electronic or distributor-free ignition system. Use caution when testing the secondary circuit; it carries a high-voltage current. When you've determined that your GMC C2500 needs a new secondary ignition, come to StockWiseAuto.com for the lowest prices in OEM parts.
