Can't find answers to no fuel pressure. Engine ran normally. Later, would not restart. Spray fuel in air cleaner opening, engines ran for several minutes, then suddenly stopped. Plenty gas in tank. Fuel rail depressing Schrader valve, no pressure of fuel present. Can't tell if pump is running. Too much ambient bells dings etc. Ignition key to on, can hear slight whir for two seconds then "click" and silence. All sounds seems to originate from top engine area. Articles mention "fuel pressure regulator". can't find that. Articles mention "Fuel Pump Control Module", control pump duty cycle, said to be in trunk area, can't find that. Would like to pull fuel pump to examine in-tank screen on pump. Can't figure how to get fuel pump out without dropping gas tank as advertised. Chillons Car Repair book is worthless. No diagrams, no specific useful information, very generic, various mustangs spread over years.
Bought a new 1966 Mustang, t'was ok. On impulse bought 2001 Mustang with buyer remorse. Poor workmanship, lousy shop support. Complaints during warranty period were ignored, mech says it road checked OK etc. Ready to push it off a cliff and buy a dependable 4 Runner. At least they run, commanded or otherwise.

 

have you changed your fuel filter it could be stopped up or it could be a fuel pump running but not pumping i have seen some on chevys do that

 

A good place to start would be to check the inertia switch to make sure it hasn't been tripped. Check your owner's manual, some switches are located in the vehicle , and some are located in the trunk. Yes, there is what we call a fuel pump driver module (FPDM). It is usually located in the trunk behind the cosmetic coverings /carpeting.
There is a fuel pressure sensor at the fuel rail with a short vacuum hose connected to manifold vacuum. The voltage and current signal comes from the ignition to the PCM that sends a pulse width modulated signal to the fuel pump driver in the trunk area. The driver module controls the fuel pump in the tank based on the signal from the PCM that gets the input from the pressure sensor. If there is no need for fuel, the driver module is kept from providing current to the pump in the tank.
Since you have no fuel pressure at all , the sensor is suspect as well as the PCM and /or FPDM ,and until you can eliminate those the fuel pump itself. Its pressure regulator is located on the pump assembly in the fuel tank. You need to check each one separately, before going after the fuel pump. Those pumps run in the area of $400-500 bucks plus the addl labor to drop the tank and replace it, If defective !
