What causes a car to backfire and do spark plugs have anything to do with it?

A backfire is caused by unburned fuel and air getting into a hot exhaust system where it ignites. Plugs have nothing to do with it. Some cars, when they are turned off, pass enough fuel and air, that isn't being burned in the now-turned-off cylinders to cause a backfire. Most of the time though it's an issue with the exhaust valve(s) in the cylinder leaking. When the cylinder compresses some of the air/fuel mix is leaking past the exhaust valve an passing into the exhaust. No fix for this short of a 'valve job' which is pulling the cylinder heads, machining the valve seats and valves yada, yada. Kinda of expensive to fix. You can test for this by doing a compression test on your cylinders. This is fairly inexpensive and can tell you if you have one of more cylinders leaking. If you cross your spark plug Wires then YES your car will Back fire.

You will still have spark, car will try to start or backfire. If no spark at all the plugs see if you have GOOD spark from coil. If coil is working then you will find the problem in between the coil and the plugs, probably a distributor component issue. The ballast resister is a possible cause also.
