    My truck keeps blowing the ignition fuse!!

    1990 GMC K1500 keeps blowing the ignition fuse. Sometimes it will try to start and sometimes it will blow before the truck even turns over. HELP!!!

    check your wiring at the injectors with ohm meter put one probe in the white or red lead and the other to ground if it shows continuity you have a short from their to fuse block check harness for rub through.

    Any after-market items you may have piggybacked onto the fuse line? Radio, alarm, amp?
