Does it have spark? If not, likely the ignition control module.
Hope this helps.

The MOST LIKELY cause of your problem is a failed distributor module. (inside the distributor) The symptoms you described can also be caused by many other things like loose or corroded connectors or even a failed Powertrain Control Module (PCM)
