I changed the oil pressure and temp sending units. I then installed my 96 gauge cluster. It all worked. I drove it around. came home shut it off and it wouldnt start. not even a click. I jumped it, and the cables got very hot. but it started. I let it run for a while. and it wouldnt start again. So I checked some wire connections under the hood. It started, but the gauges stopped working. Help!
