I had a 90 P/U V6 xtra cab 4X4, it had the same problem but I cannot remember if it was the sending unit itself or the connection. Once I get my garage cleaned out (we just moved into a new house) I'll check it out better, I know I have oil pressure, I can see it pumping up into the valves and I have no ticking. I really have ALOT to do to this truck, she needs body work and I want to lift it up. I want to do a custom interior. I got it last summer and she really needed serious work, front end, complete brake system, tires, suspension. SHe was a mess, but now she looks good and runs great. SO I got some welding and sandblasting to do, but hey thats what I wanted a PROJECT, for the winter. Not much to do after hunting season and before camping season.
