    Default Re: fuel pump not pumping

    If I was working on it, I believe I would disconnect the fuel line from the carb, push a hose on the end of the line and run the pump with a jumper and see if you can pump gas into a gerry can. See if the pump keeps pumping or it just runs and nothing coming out.

    We did that and the pump is working. Any other thoughts?

    Did you let the pump run for several minutes? Might also try the same test with the relay installed. Just disconnect the green wire from the alternator and hook a jumper wire for the battery to the green wire and see if it will run the pump for 5 minutes or more.

    To be frank, I'm 40 miles from this boat, It'd save myself and the owner a lot of time and me some trips back and forth if you could give me some additional advice on what to do if the pump does pump for five mins, but the boat still wont start, then what next? ...And if the pump doesn't continue working for five mins, then what do we check after that?

    I'd greatly appreciate any help you could give. Thanks.

    If the pump works, check the carb. if it doesn't work it could be a faulty relay or pump.

    Im assuming its a holley 2 bbl or 4 bbl. If ts a 2bbl its a Model 2300.I would check the needle and seat to make sure its not stuck.
    Does the carb look like this http://www.holley.com/data/products/...e0-80402-1.jpg

    If the pump is flowing fuel (when jumpered) and the engine will run off the prime then its still fuel related.
    Next place in the is the needle and seat.
