I was driving my '92 GT today and all of a sudden the oil pressure guage dropped to nothing. I didnt think anything of it because I thought it was just a problem with the sender so I drove it for about 10 minutes and then it started ticking slightly from the top end so I immediately pulled over and shut it off. Then I got a ride home and went back and towed it with my truck. The car only has just under 80,000 miles on the original motor. Does this sound like a bad pump?? I have never had one just go bad on me like this before. I cant think what else it could be other than the shaft from the dizzy to the pump coming loose but I just cant see that.
