3.9V8i Ignition problems
« on: January 16, 2007, 18:48:26 »
:?  Help. The above started one morning then cut out. Turns over lovely but will not fire. Got fuel to the plugs but very weak spark. Changed the coil and ignition amplifier to no avail. Tested the resistance on the pick-up in the dizzy and all was good. Still got a very weak spark. All plugs, leads, rotor arm and dizzy cap were changed less than a year ago with very little mileage since. Any ideas?

Does it run if you put a 12v feed from the battery to Coil+ terminal??
