Consider buying a new set of spark plug wires while you’re at it. Since you’ll be disconnecting them anyway, replacing them now can prevent future issues and ensure optimal spark delivery. Spark plug wires can deteriorate over time, leading to misfires and poor performance. Replacing them along with the ignition coil is a proactive maintenance step that can save you trouble down the road. Check your owner’s manual or a reliable online resource for the correct spark plug wire type for your 1992 Firebird.
With the right tools and the correct ignition coil in hand, you’re ready to move on to the next stage of the replacement process.
Disconnecting the Battery for Safety
Before you even think about touching those spark plug wires, the very first thing you need to do is disconnect the battery. This isn’t just a suggestion, it’s a crucial safety precaution. Think of it like turning off the gas before you work on a gas stove – you’re eliminating the potential for sparks and shocks. Dealing with high voltage ignition components can be dangerous, so we’re going to take this step-by-step to make sure it’s done right.
Locating the Battery
The battery in your 1992 Firebird is located in the engine compartment. Typically, it’s pretty easy to spot – it’s a black rectangular box with two terminals, one positive (marked with a “+” symbol) and one negative (marked with a “-” symbol). Sometimes, it might have a plastic cover over it. Go ahead and remove that cover so you have clear access to the terminals.
Disconnecting the Negative Cable
Tools You’ll Need:
You’ll need the right tool for the job to avoid damaging the battery terminals. A wrench specifically designed for battery terminals is ideal. These wrenches are usually around 8mm or 10mm, and they often have a slightly angled head to provide better leverage. In a pinch, you could use an adjustable wrench, but be careful not to over-tighten it. Over-tightening can strip the terminal nut and lead to a whole new set of problems.
Steps for Disconnection:
With your wrench in hand, locate the negative terminal (marked with a “-” symbol). Loosen the nut that secures the cable clamp to the terminal. You don’t need to remove the nut entirely, just loosen it enough so you can wiggle the cable clamp free. Once the clamp is loose, carefully twist and pull it straight up and off the terminal. Avoid touching any metal parts of the car with the wrench while you’re doing this, just in case there’s any residual charge. Once the negative cable is disconnected, move it aside and make sure it can’t accidentally come into contact with the terminal while you’re working. You can use a bungee cord or even a rag to keep it safely out of the way. Double-check that the cable is secure and then you’re ready to move on.
| Tool | Size | Alternative |
|---|---|---|
| Battery Terminal Wrench | 8mm or 10mm | Adjustable Wrench (use with caution) |
Disconnecting the Positive Cable (Optional)
While disconnecting the negative cable is generally sufficient, some mechanics also recommend disconnecting the positive cable for added safety. If you choose to do this, follow the same procedure as you did for the negative cable: locate the positive terminal (marked with a “+” symbol), loosen the nut, and carefully remove the cable clamp. Remember to keep the positive cable away from any metal parts of the car, and especially away from the negative cable and terminal. Once both cables are disconnected, you’ve eliminated the risk of accidental sparks and shocks, and you can proceed with replacing the ignition coil with confidence.
Extracting the Old Ignition Coil
Alright, so you’ve got your new ignition coil ready to go, but first, we gotta get that old one outta there. This part’s usually pretty straightforward, but let’s walk through it step-by-step to make sure things go smoothly.
Disconnecting the Battery

Gently wiggle them back and forth as you pull them off. Avoid yanking on the wires themselves, as you could damage them. If they’re really stuck, a little bit of electrical contact cleaner can help loosen them up.
Removing the Ignition Coil
With the wires disconnected, you’re ready to remove the ignition coil itself. It’s usually held in place by a couple of bolts or screws. Locate these fasteners and carefully remove them using the appropriate wrench or screwdriver. Keep track of these fasteners, as you’ll need them to install the new coil. Depending on the specific setup in your Firebird, you might encounter a small bracket holding the coil in place. If so, you’ll need to remove this bracket as well, typically by removing a couple of additional bolts. Once the fasteners are removed, gently lift the ignition coil straight up and out of its mounting position. It might require a little wiggling to break it free, especially if it’s been in there for a while. If it feels stuck, double-check to make sure all the retaining bolts and brackets are removed. Avoid forcing it, as you don’t want to damage any surrounding components. If you encounter significant resistance, try applying a small amount of penetrating oil to the base of the coil where it mounts, wait a few minutes, and try again. Once you’ve successfully extracted the old ignition coil, take a moment to inspect the connector terminals for any corrosion or damage. If the terminals appear corroded, use a wire brush or some contact cleaner to clean them up. This will ensure a good connection with the new coil. Also, take a look at the area where the coil was mounted. Clean up any debris or rust that might have accumulated there. This will prevent future issues and ensure a secure fit for the new coil.
