Agreed. I pulled my hair out over that ground on the bottom of the block. Called Casey "Man why won't this thing fire? - Crawl under the truck, check this ground, call me back in 5 minutes I want to hear it running" done.

Yea I know their were two black wires on passenger side harness that didnt have any sensors to them we grounded one but not the other. Prob try and ground the other and see what happens.
