Here's what we discovered today. Coil #3 has a black/yellow wire. Which ever coil we moved the blk/yel wire to, that coil would not fire. We swapped his new transistor with the old one and had the same results. Using a DMM at each colored wire attached to each coil, all 3 showed the same voltage drop while the engine was being cranked. It's as though the circuit for the blk/yel wire is not opening to fire the coil.
