If you cant hotwire the starter and get it to work, all the other ignition and clutch switches don't mean shit, check your positive wire comeing from the positive battery cable to the starter itself, you can try the jumper cables right to the starter postive side, but put it on the starter first then the battery terminal
P.S. Don't use the junk jumper cables. Also since its a 93, does it have cruise control? Make sure you're not jumpering the wrong switch on the clutch pedal.
