Why won't it start?

its possible u may have burnt out the pump it uses the fuel to cool the pump

the fuel pump is cooled by gas so if u run it low alot or {OUT} it can burn it up
keep that tank at 1/4 or u will pay!!!

Your fuel pump is on its way out it's giving you signs what you see is what normally happens when fuel pumps go out best of luck to you

Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.

Check ur engine

Won't crank or won't start.

the fact that it won`t turn over is just a coincedent it happened when you ran out of gas.i`m assuming that you mean the motor won`t turn over at all and not that you mean it will turn over and not start.if it is the latter then the fuel needs time to fill the lines and pressurize the fuel system while cranking over.
