Do you get power to the solenoid when you turn the key to start? Check the wire from key switch to solenoid for abraded insulation/short. I had a similar intermittent no start on a perkins 4-108 that was a shorted wire to exhaust manifold. If you get no shorts/no power to solenoid, are you getting power out of the key switch? you said it used to start after jiggling wires near starter. I'd start there & trace back for breaks/shorts/mouse sign.
