I have a 1990 mercury 90 horse with the oil injection. I had taken the oil tank and lines off, and put everything back on. When I turn the motor over to try to get oil to come out of the outlet hose into the fuel pump, I get nothing. Does this sound like a weak oil pump?
I went ahead and took the oil pump off, is there a way to test and see if it is bad or not?
