w-lewis Make sure you have power going to the MSD box and good grounds. Make sure the battery is over 10.5 volts. Even this is boarder line for an MSD box. Check the wiring for any rub marks that would cause a short to the box or ground. If all this seams OK, Go get another box and install it. If it is the box, and the box is new and in good shape, sent it back to MSD for repair. I had a new one that didn't work, they fixed it free. I carry a spare setup, MSD 6AL box(2) 1 distributor complete, 1 HVC coil and the tools to replace all on the side of the road. Who distributor are you using, MSD or Ford? If you goto the MSD web site, there are some simple tests for checking the system. Swap parts from another car that you know are good, There is a test for checking spark by tapping to ground one of the wires, You should see good spark. Make sure the battery is strong. With mini starters and gear reduction, these starter will crank at 9.0 volts. They little amp draw. Remove plugs and unhook coil and crank motor over to clean out the gas. MAKE SURE there is no spark there to light this up. I put towels over the holes when cranking. Stay away from Starting fluid.
