i have recently installed a msd 6al box, coil and wires, ever since i installed this new ignition system i've been having problems cranking.it will sometimes lose spark all of a sudden, one time it cut off on me doing about 35, i pulled over and it fired right up. and today i washed it and went to start it and it wouldnt start.i tried a diffent coil, no spark, tried to disconnect the msd box, no park, im stumped now.
