Putting a volt meter against the coil I found out a few things. With the ignition on(all the tests were done this way), and the truck NOT running, the pos post on the coil came to a steady 6v. The neg post was a steady 1v. Disconnecting the pos wire from the coil and testing that came to 12v, the neg had 0v. With the truck running the pos post fluctuated from 2v to 10v. The neg post had a steady 6v.
I'm thinking this brand new coil is bad, but I suppose there is a possibility that the starter relay is bad, causing the pos side to fluctuate like that with it running. But I figure that if the relay was bad I would have seen something when I pulled the pos connector off the relay and picked up 12v.
What do you guys think? The truck is parked in a parking lot and they are towing it on Saturday morning. If I can't get it moved tomorrow I'm screwed.
