I tried to change my spark plugs on my truck the other day but found out that there is some kind of cover or plate around the plug wire end where it slips into the spark plug. i tried pulling at the end like i would on any other vehical but this cover around the end seems to keep it on. Any advice or tools that i need to use to take that cover off?

Its a heat sheild. I've found its best to use spark plug boot pliers to remove them. Twist/turn the boot at least 1/4 turn before pulling. Use silicon grease(made for plug wires) on inside of each boot when reinstalling them to help next removal

Could that be the ignition coil? Some are directly over the plugs. You need to unbolt it and it pops off the plug.
On older models that %26quot;cover plate%26quot; is actually a heat shield to protect the wires from the heat of the exhaust manifold and do not prevent you from removing the wire. Sometimes the wires are hard to remove when they have been there too long. Can this be the case?
I sure don't know much about GMC but my Honda has the spark plug coils to slip through the holes and female right on the spake plug nipple tips, be able to take them off and separate from the engine that you have to use the Allen Wrench to un-screw the Allen-Wrench screws so you can take it off.... good luck.
