MSD people, truck wont start

[PetaKane]

Truck is getting fuel just no spark. I've got an MSD 6AL box, Blaster 2 coil and here is my problem. The truck will not start unless the 12V switched wire is connected to a constant 12V source, then it'll run for a few seconds and die again. When I connect it to a 12Switched source, it'll crank and crank and crank but won't fire up. I've checked my 12Switched sources with Multi-meter and they are just fine. I'm scratchin my head on this one, does my truck just want me to kill it?

Have you tested the coil? I'm not sure but I think Greg72 had this problem a while back. Find out more though before you go buy a new coil. Wish I could help more.

Ditto on that. He has helped me out alot over the last year or so. Also on the MSD website there are ways to troubleshoot, and ways to test to see if the box is bad.
