it very well could be a coil. trigger or a module, id start first at the trigger those thin wires going into trigger have a problem with breaking at the point where they connect into the trigger grab a vom meter and measure the ohms on the four pairs of trigger leads you should read between 45 to 50 ohms on each seperate pair of leads if you read zero ohms you got a trigger problem
Thanks for the reply chitown. I'll try that when I get home. To diagnos a bad coil, can I just switch the one I think is bad with a good one? Or is that a bad idea? Thanks
yep thats the way to check a coil, swap it with a working one and see if you get spark, if ya do get spark you got a bad coil, if not you got issues somewhere else good luck
