Do you have more than 4 gallons of gas in the tank? Some models won't **** to prime with less than that in the tank. This is mostly an issue when there is air in the lines. There is usually a screen filter on the pick up, but blowing that out should have taken care of it at least for a few days. Another possibility is a pinhole leak in the line between the tank and the pump. That lets the pump **** air, which will not let it **** gas. There could be a larger in-line filter between the tank and the carb filter. Let us know if you find out what it is.

    Probably not. Can you put a rag around a air hose nozzle and blow into the gas tank with a compressor to see if the fuel will go all the way to the carb that way? If so disconnect the fuel line at the carb and try that. Be ready to catch the fuel if it flows. If it does not, have you checked for a pinhole leak in the line? What year is this and how many miles?

find the filter pull it off and clean it if u cant clean it replace it they usally are cheap on older vehicles but with the filter off turn the car have someone turn the car to the on position so the pump is pumping and see how good it is coming out of the line if not very good then your gas tank line to the fuel filter is clogged but if its fine check the next fuel line the one on the fuel rail there is a bolt on the fuel rail crack it open and have someone turn the key if gas comes out then you are getting fuel and that would mean your injectors are bad
