Check resistance on trigger base wire pairs. (Easy)

Physically swap at least one ign. coil to the other side. Is port side still sparking on all 3? If yes- you may have a bad control module. The black box on top of the engine with lots of wires. Before declaring a component dead, unplug, inspect, replug all connectors you can reach on the engine. All conductors in the plugs should be clean. No green corrosion allowed.
