My buddy just bought a 87GN well the motor was not together so he got it put together and when he got it out the shop he was on his way home and stopped at a stop sign and then when he pulled out the car went dead....His headlights and interior lights would come on but when he tried to crank it it wouldnt say nothing it wouldnt even turn over or even make a click noise its like he doesnt even turn the switch anyone have any clues to help him out???
