Identifying and Fixing GMC Envoy Ignition Coil Problems

For vehicles, everything begins with a spark. This spark is powered by the ignition coil, and when the ignition coil fails, the journey cannot even begin. This reduces the impressive GMC Envoy into a massive box in your garage. Ignition coils play a vital role in your engine performance, which is why, as an owner, you should familiarize yourself with its operations and its possible failings. Here are some ways on how to diagnose GMC Envoy ignition coil issues and what you can do about them.

Engine won't start

After a rainy night, you find that your GMC Envoy refuses to start. This could mean that the cylinders of your ignition coils may have cracked and moisture seeped into it. Check the coil pack, if you confirm that moisture has come in contact with your ignition coils then take them out and dry them. Clean the ignition coil packs as well and make sure that you dry them completely afterwards. If the ignition coil only has a hairline crack then you should be able to start the car. However, the crack will cause your vehicle to stall in the future as the crack disrupts the coil's ability to power sparks.

Stalling

Ignition coil related stalling can be hot or cold and both cases will leave you stuck on the side of the road. Hot stalling is a result of hairline fracture on one of the coil's windings. Normally, ignition coils can take the high temperatures that the engine produces. However, this resistance decreases with a bad coil. So as the heat expands the bad coil, the gap from the crack disrupts the connection, and power fails to reach its destination. You can temporarily fix this by allowing the engine to cool off for a few minutes before starting again. On the other hand, if you stall when the temperature's low, like when it's raining or snowing, then it means that moisture has gotten into your ignition coils. This results in a weak spark. When the spark is not powerful enough to make the engine run, your vehicle stalls. Try restarting your engine and let it idle, before continuing your drive, this allows the coils to warm up.

Misfires and noise

When accelerating on the road, you suddenly find your engine hesitating. This is then followed by the sounds of your engine coughing, and the feel of your engine jerking. This means that your ignition coils are producing weak sparks that is underwhelming your engine. Even if the vehicle doesn't stall, make it a point to stop anyway. Turn off the engine then try restarting it. Better make sure that you check under the hood when you get home though. Misfires are common in old engines, but sometimes, it could mean that one of your ignition coils need replacing.

Ignition coils are normally sturdy and doesn't need scheduled replacing like the spark plugs. And although most ignition coils are recommended to be changed every 60,000 miles, some can last for longer. However, there are a lot of issues that could cause the ignition coils to fail. Your GMC Envoy ignition coil is essentially an electrical transformer. It contains the primary and secondary windings, which release electric current. The ignition coil produces the spark necessary to start internal combustion. Because of the constant electric current running through the coils, they are prone to the usual wear and tear problems. Here are ways to prevent your ignition coil from failing.


Keep insulation stable


The wires in the ignition coils must be fully insulated to properly function. Any change to the insulation negatively affects the coil's efficiency. The worst things that could happen is that, if the insulation wears thin enough, it can cause the wires to come in contact and results in a burn out. The good thing is that a properly functioning coil can have an effective resistance to any temperature, high or low.


Keep the wires dry


One of the worst things that can happen to your ignition coils is getting wet. When you encounter a drive that requires you to submerge your vehicle in water, make sure none of the water seeps into your ignition coils. The only thing that keeps moisture at bay is a rubber seal. If the rubber seal fails, moisture can reach you ignition coils. Wet ignition coils causes malfunction, misfires and could cause the spark plugs short-circuit, which effectively kills the ignition coil wires.


Keep the cooling oil clean


Since electric current runs through the ignition coil wires, the heat that they generate can cause the wires to melt. To keep the wires cool, oil flows through the ignition coil. However, overtime, the oil accumulates dirt and burns out the entire system. Make sure that the ignition coil's oil is clear. Change it regularly to avoid soot from building-up.


Look for damages


Prevention is better than cure, and in this case, also cheaper. Make it a point to check the condition of your ignition coils. Although sturdy, the ignition heat and vibration causes the ignition coils to expand and crack. In addition, check the coil's efficiency with a multimeter as well. If you see even a hairline crack or any of the two coils fail in the multimeter test, then replace them. When planning for a long drive, check if any of the coils need replacing. This will prevent you from being stuck on a road in the middle of nowhere.
