Hello folks,Great forum. I have a 1994 Marathon that will only fire on one side of the ignition coil.I replaced the coil but the same thing is happening.Could it be the pulsar coil or the igniter? What is the beat way to troubleshoot these systems?

Welcome Glenn,

if the coil fires on one side, the ignitor and purser coil are good. that coil fires both sides at the same time, so the problem is either the coil, plug wire or plug. are you sure the spark plug is not sparking or is one cylinder not hitting?
