MSD mess

You guys rock!!! thanks for all the ideas. With all the input I found my prooblem. It seems the MSD box needs a constant 12 volt switched power supply (small red wire), I had attached it directly to the fuse box and when the car was cranked the voltage would drop and thus not supply power to the box. As soon as I found a new source BINGO she fired right up!!!!! Again; thanks to all who took the time to respond.:nike:
