Do you have power to your ign. switch? There are fuses that control the ign circuit as well, one of the two big fuses and (if memory is correct) theres one in the fuse block. With this issue we have changed fuses, ign. switches, and a couple relays. Most common are fuses or the ign. switch. If no voltage or low voltage at ign. switch check the positive battery cable at the battery. The smaller cable (approx. 10 gage) makes a connection there that tends to get corroded and will also cause this issue. Hope this helps you.
