I just bought this 1994 2.5l YJ and the oil pressure guage wasn't the right one, so I replaced it. It worked for about 2 days and now just sits at 0. I replaced the oil pressure sending unit today and still no move in the guage. Any suggestions.?
I figured it out. I realized that the gauge I got sent, the needle was to long, so when I installed it, I didnt realized that it was pinched not being able to move.
