1.Run a jump wire from neg. on the battery to bellhousing/starter motor bolts, that would check earth.
2.Then, disconnect pos. on battery to starter motor input and run a jump lead. This would check that cable.
3.Run a jump wire from starter input/switch terminal on the solenoid and touch it on the battery positive. This would bypass the ignition switch.

My guess is the main wire from battery positive to starter motor is buggered.
