GMC Sonoma Ignition Coil
In GMC Sonoma cars, the Ignition Coil is a very vital component that helps in converting the low voltage from the GMC Sonoma battery into a high voltage needed to fire the air/fuel mixture in the cylinders. This one is made up of first and second coils of wire that are flown around an iron body and are invariably insulated by either plastic or epoxy. According to the type of the ignition system, the coil may be connected with the triggering device through terminal or directly with the spark plugs. Even when it comes to the types of ignition systems which include distributor ignition, the coil-on-plug ignition and the wasted spark systems, they work in different ways in ensuring the voltage gets to the spark plugs. The ignition coil can go bad in some cars and lead to problematic situations such as misfires and rough idling, poor performance and for that to be rectified, it has to be diagnosed and replaced.
Each OEM GMC Sonoma Ignition Coil we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
GMC Sonoma Ignition Coil Parts Questions & Experts Answers
- Q: How to check and replace the pick-up coil on GMC Sonoma?A: To check the ignition coil, start by connecting one lead of an ohmmeter to the terminal of the ignition coil lead and the other lead to the ground. Flex the leads by hand to check for intermittent opens, and the ohmmeter should always indicate infinite resistance. If it doesn't, the ignition coil is defective and needs to be replaced. Next, connect the ohmmeter leads to both terminals of the ignition coil lead and flex the leads by hand again. The ohmmeter should read a steady value between 500 and 1,500 ohms as the leads are flexed. If it doesn't, the ignition coil is defective and should be replaced. To remove the ignition coil, start by detaching the cable from the negative terminal of the battery. Then, remove the Distributor cap and rotor, and if necessary, remove the distributor itself. Remove the spring clip from the distributor shaft and mark the distributor tang drive and shaft for reassembly. Set the distributor in a vise with a shop rag to protect the shaft, and use a hammer and punch to remove the roll pin from the distributor shaft and gear. Lift the ignition coil assembly straight up and remove it from the distributor, noting the order in which the pieces were removed. Reassembly is the reverse of disassembly.
- Q: How to check and remove the Ignition Coil on GMC Sonoma?A: To check the High Energy Ignition System (HEI), begin by disconnecting the battery's negative terminal. Test the coil for opens and grounds. On the high scale, connect the ohmmeter leads; it should show a very high or infinite resistance value. On the low scale, check the coil's primary resistance, which should indicate a very low or zero resistance value. Also, check the coil's secondary resistance on the high scale; it should not show an infinite resistance. If any values are off, replace the coil. For removal, unplug the coil's high-tension wire and electrical leads, and remove the mounting nuts to take out the coil. The installation process is the reverse of removal.
