How do you put spark plug wires in the right place on coil pack a 1995 Chevy Cavalier?

The firing order for a 1995 Chevy Cavalier's 2.2L engine (the most common engine in that year) is 1-3-4-2. However, you MUST find the firing order specifically for YOUR engine as there may be slight variations depending on the exact engine code. Look for a sticker under the hood or in the owner's manual. This sticker will show the firing order and/or a diagram of the spark plug wire routing.

Assuming you have the correct firing order for your engine, here's the general process:

1. Identify the cylinders: Locate the cylinders on your engine. They are numbered sequentially, usually starting from the timing belt side of the engine (though again, verify this with your specific engine's information).

2. Locate the coil pack: This is usually mounted on top of the engine near the spark plugs.

3. Identify the coil pack terminals: Each terminal on the coil pack corresponds to a specific cylinder. The terminals are often numbered or have a diagram cast into the coil pack itself. This is critical! Some coil packs have the numbers visible, some don't. If you can't easily identify which terminal is which, use a diagram or consult a repair manual.

4. Connect the wires according to the firing order: Connect the spark plug wire from the correct coil pack terminal to the correct spark plug. Follow the firing order precisely. For example, if your firing order is 1-3-4-2, the wire from the coil pack terminal designated "1" goes to the spark plug on cylinder #1, the wire from terminal "3" goes to cylinder #3, and so on.

5. Check the routing: Ensure the wires aren't too close to hot components, pinched, or kinked. Route them neatly to avoid interference.

6. Double-check: After connecting all the wires, double-check each connection to make absolutely sure you have the correct wire on each spark plug and coil pack terminal.

Using a Diagram: A repair manual (like a Chilton's or Haynes manual) or a reliable online source for your specific engine code will be invaluable. These sources will have diagrams showing exactly where each spark plug wire should go.

Important Safety Note: Disconnect the negative battery terminal before working on your ignition system. Spark plugs and ignition wires carry high voltage and can cause a painful shock.

Without knowing the precise engine code of your 1995 Chevy Cavalier, this is the best general guidance I can give. Always confirm your firing order with documentation specific to your vehicle. Using an incorrect firing order can damage your engine.
