Today I ran a 16 AWG jumper from one of the coil's mounting bolts to the Tie Bar. I had already installed a 4 AWG cable from the Tie Bar to battery's negative terminal. Years ago I had run a 16 AWG jumper between both subframe wire junction points. Today I pulled the bolts, ran a tap down the holes, squirted in CRC 2-26, coated the bolts with neverseize and reassembled. Also coated the ecm pins and connectors with 2-26.
This is a PITA task but your credibility is high based on last weeks performance. Didn't go for a run today but the bike started instantly. Faster than usual.
