More troubleshooting today. Pulled plug on left side(the cyclinder that isn't running), and got no spark when holding it near the dcylinder head. Did the right side and I get a nice blue spark. So it's definitely an electrical problem where I'm not getting a spark on the left cyclinder.

Tried to check the voltage coming into the coil with my multimeter by putting the positive/red lead from the multimeter in the positive incoming wire at the coil, and holding the negative/black lead to a frame ground, but got no reading on the multimeter. Checked the right side and got the same result. Isn't it possible to get a 12 VDC voltage reading going from the coil leads by cranking the engine over while doing the above with a mutlimeter?

Anything else I can do?
