Question about Ford F-150
The only way to check the fuel system is with a pressure gauge. the rail pressure should be around 39 psi . make sure the fuel filter is ok before testing, if the pressure is low check the fuel regulator if ok check the fuel pump, most in tank pumps have a sock type filter make sure its ok , the fuel pressure should hold for a few minutes after being switched off, if not the pump return valve may be faulty, the fuel flow must be checked also , if you don't have a flow meter do the following, divert the fuel rail return line to a container , start the engine it must flow around a pint in thirty seconds for the pump to be ok.
