Had another no spark problem today, of course, at work when I was heading home. Truck wouldn't start, checked the distributor cap, looked good. Pulled a plug to check for spark, had buddy crank it and all of a sudden I had spark and truck fired and was running on 3 with one in my hand. <img src="/forums/images/graemlins/zombie.gif" alt="" /> I got home and checked the resistance on the signal generator, was a little high, so I replaced that, hoping it fixes the problem. Anyone had anything similar with a Jacobs ignition? <img src="/forums/images/graemlins/confused.gif" alt="" />
