2002 Mercury Mountaineer Repair Question
Mercury Mountaineer Fuel pump Problem
Answer
have the fuel pressure checked first.
Roy
How do I do that? My engine knowledge is limited, but I'm a smart guy and can follow directions.
you need a pressure gauge that you can rent at a parts store.
Roy
Ok. That I can do. I'm assuming the pressure gage has instructions? Is this something I "rent" or purchase? Pep Boys have something like that?
yes, peps does have it and it is a rent. instructions are included
Roy
Also if there's low pressure, what does that tell me? fuel pump? injectors or simply that I'm majorly screwed and it's gonna cost a gazillion dollars to fix?
forget about injectors. they would be an issue cold or hot.
yes, the pump would have to be replaced if it is low
Roy
so if low pressure, fuel pump. got it. one mechanic did say above symptons could very easily be injectors. Tempature outside has nothing to do with anything as I live in Los Angeles. Injector guy said if injectors clogged, this could happen and once engine eventually starts, and injectors stay warm, car runs fine. once injectors sit and get cold again, cranking needed. He recommended trying a product called Zmax. helps clean injectors. Is he off his rocker? If low pressure, fuel pump, but what if pressure is fine? Injectors?
once again, if the injectors were the issue, it would be all the time not just cold and there would be many other complaints
Roy
Thank you. i've gotten repair quotes for a fuel pump at roughly $750 including labor. Does that sound about right?
