Question about Ford Explorer
Bad Fuse,pump relay,Fuel filter,weak fuel pump,pluged fuel filter in the tank.bad pressure regulator,check to see if the pump runs in the tank.you should here it run while you crank the engine. if you can then check the filter.it should be open,not restricted.then check fuel pressure,at the fuel rail,with a guage 36 to 40psi is normal. Any less pressure will give poor performance.Check to see if the pressure regulator is or has ben leaking gas into the vacumn line to the intake manifold,if you can see smell,or detect any raw gas i would suspect a faulty pressure regulator.And it may be returning the fuel pressure back to the tank instead of controlling the fuel pressure to run the engine.
