Having problems with your 1991 Toyota Pickup ?
22re engine , I replaced the oil pressure sending unit , tested the guage and I still cant get oil pressure reading on the guage . I hooked up an manual gage and the engine has 70 lbs oil pressure at idle cold , and 45 when hot . Why wont the factory guage work?
Either the gauge itself is bad or the ground is insufficient. Start by checking the ground first. That`s free.
