Intermittent fuel pump engagement when turning key to start position (2001 Ford Taurus - 3 litre). When fuel pump engages, engine starts right up. Obviously, no starting when it doesn't. Have replaced 20A fuse and multi-pronged large fuel relay fuse in the power distribution box under hood. Problem still persists. Does fuel pump need replaced?
Try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.
Try and replace the oil sending unit,it has a cut off for the fuel pump.This could be leaking,or not,but replace it any way,it isn`t expensive,and it is part of the fuel system wire routing.If the fuse for the fuel pump is blowing,then the fuel pump is most likely bad.I hope this is some help,if so,please let us know,thank you.
