Cranked up the 77 FJ40 yesterday and noticed there was no oil pressure reading on gauge. Shut engine down and starting looking. Took gauge cluster out and checked continuity of wire from oil sending unit to wire on plug that goes to oil pressure gauge and had good continuity. Screwed oil filter off and cranked up cruiser and oil was pumping very good up through oil filter housing so I don't have an oil pump problem, thank goodness. So, I believe that I have a oil sending unit problem or an oil gauge problem. How do I check each one to isolate the problem. Thank you very much..
