I have tested the MSD grounding the white wire. I even went all the way to the ECU connector. For a little background, I got the car out of the body shop in August and drove it for about six months. It went back in the shop for some paint repair for a few months. They also did some welding on the car, but the battery was disconnected. When they went to start it, it wouldn't. I had to uploaded the Global File and it finally fired up. Since then, it was hard to start after sitting for a week. Now, it won't start at all.

Quick update. Using the eeny, meeny, miny, moe scientific method, I determined it was the MSD box. Thanks for the help.
