Try spraying starting liquid at the throttle body and then start.If it starts and runs smooth then its faulty fuel pump and clogged fuel filter issue.--------
A car that cranks over but doesn't start, in many cases will be
due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or
crank sensor. Also these problems are related to faulty spark plug. Check the
spark at spark plugs when you start the car. Do you notice any spark. Actually
you should see. If in case there is no spark then it's a spark plug problem.
Also the coil pack gives power to spark plug. So check the voltage at coil
pack. It will show 12 volt. If there is no voltage noticed at coil pack then
its faulty coil pack that has to be replaced. If all the possible options
checked out ok then check the car starter. The starter gets power from battery
to start the car. If the starter is faulty then it will not let the car to
start. Also check and confirm that there is fuel in the car. If its very low
fuel then in some cases this causes the problem. Also check and confirm that
fuel pump is functioning properly and the fuel filter is not clogged. One of
the easiest ways to check for a fuel pump related problem is to spray a little
starting fluid into the air intake while trying to start the car. If the car
starts momentarily, then there's a good chance the fuel pump is not working or
the car is out of gas. You can also listen for the fuel pump's humming sound
when the key is first turned on. Also if a inoperative fuel pump is suspected,
a good technician will always check to verify there is power and ground being
supplied to the pump, to eliminate the possibility of a bad relay or electrical
issue. Fuel pressure can be checked with a pressure gauge and if there is
pressure, pulse can be checked at the fuel injectors in several ways including
the most common, with the use of noid lights. If the injectors don't have pulse
the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks.

Peace I think my problem is in the sensor the fuel is flowing this information was very helpful thanks !!!! Peace

It still could be the fuel pump to test it open hood unplug the fuel line turn on key for a second if the hose didn`t squirt fuel then the pump is not working
it could be fuel filter but not sure
SOURCE: Egine turns over fine, but the fuel pump does not
fuel pump itself is most likely going bad.
SOURCE: Car will turn over but won't start. Through the
No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.---------
To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.--------
The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
-----------
If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.---------
This will help.Thanks.Helpmech.
Testimonial: "Thanks. That was the best answer yet.I didn't want to hear that the PCM might need to be replaced but the car has served it's purpose through the year"
