Re: help!! no fire to coils 1988 omc 2 liter
Unplug the large red connector on the port side of the engine. This will remove the key and lanyard switches from the circut. Use a remote starter switch at the starter solenoid and see if you get spark. If you do, then isolate which switch or wire is causing the problem. Just remember the engine will not shut down unless you reconnect the red plug again. The key and lanyard switches ground the ignition system, it's not a 12 volt powered system like a car.
