1996 ford exploree sputters then it kills on start up what could be the problem? I have already changed the fuel pump alittle while back could that still be the problem ?|||FUEL FILTER CHANGED LATELY????|||Could be a plugged fuel filter,bad intake manifold gasket,poor connection at map sensor.What size is the engine?|||Check and see if any codes are set.Is check engine light on in dash?Look at plugs and wires.
