Spark Plugs and Wires
Chevy Celebrity
Ford F-150

What could be the reasons for one cylinder not working if the spark plugs and wiring have been changed on a 1989 Chevy Celebrity 2.8 liter engine?

Run a compression test before you spend too much time checking out other potential problems. If the compression tests good, try swapping the fuel injector with a good cylinder and see if the dead cylinder moves.
