car is not firing and wont start

I have a 1989 cutlass Ciera with 3.3 v-6 and when you turn the engine over it appears to be not firing and it want start. Can you tell me how to fix this car where it will fire again so it will start again. Thanks

No magic answer here, do you have spark at the plugs, will it start by spraying carb cleaner into the intake, you have provided no info here.

No the car was running but in need of a tune up, so i pull one of the spark plug wires off to check its condition, and forgot that i took it off and started up the car to pump my tires up and the metal plug cover was popping due to it was laying beside the heat sheild so i heard a tapping sound so i cut the car off, and reinstall the plug wire and it haven't started since, so what can i do to get fire back so the car will start again. Thanks

Ok no spark, check the fuses, if ok, it could be the ign module or the crank sensor, or the wire from the icm to the crank sensor. The procedure to do this can be found at autozone.com, repair guides.

I believe you have a distributor on that car? If so you could have done some damage to it with the plug out ,check you cap for arc jumping and make sure your dist is working properly

Pretty sure it is DIS.....
