    85 horse Merc w/no spark

    New to this forum today! I have recently purchase a 94 Intruder hull with an older Merc, 85 horse, with a pump. The whole thing has been neglected and comes in a kit form. My question today seems simple, but? There is no spark. It is a four cylinder with electronic ignition, probably late 70's...
