Re: oil pressure gauge

Does it go all the way up with the engine not running? Make sure the wire is still connected to the oil pressure sending unit.

Re: oil pressure gauge

sounds like you have a bad oil oil press. sensor . a common enough problem on 3rd gens. . located above oil filter , not too bad to replace . be careful of old brittle plastic elect. connector on sensor . good luck .
