msd no fire need help

Could be your box.

Does your red light come on and stay on when you turn the key to run?MSD say's it will turn off and on but I had and still have not ever seen the light go out unless the box is bad.

If not then there is a cheap as transistor in your box that is shot. If it is fairly new MSD will repair it for you and may not charge you.

If you just put it in you may have wired it incorrectly so that it wont throw spark when you crank but will when you release the key.

I had my MSD box go bad in less than 1500 miles......try the spark test as described above that will tell you the story.


Good luck.
