Hi :) Some times when you replace a fuel pump you have to turn the engine over till the air is pumped out of the fuel lines. I spray gas into the air intake with a spray bottle while someone else is turning the engine over to help me prime the fuel lines. if you don't get the engine to fire with the spray bottle there is no spark and you need to look else where for the problem.
When you have your hood up in the air can you hear the starter trying to make a clicking sound or no sound at all with the starter ? Starters also go bad too and some times it is intermitten some times as well. You can use a multimeter if you know how to use one that you can use one to test the starter red hot plug from the battery to it.

Is there a light on the dash that says SECURITY? These anti theft systems have been known to disable fuel.

The new 2010 Fusion has what Ford calls, "one touch" start. If you turn the key to the start position and let go, the starter continues to turn. The ECM takes over the starting process and monitors the number of times the crankshaft rotates as it adds fuel and ignition for the engine to start. On 2010 Fusion's built before August 2009, there is a problem with the starting process. On occasion, the starter will turn the engine, but the engine will not start. The starter will not time out and the only way to stop the starter is to turn the key to the "off" position. TSB 09-19-1 is supposed to take care of the issue by replacing the ground cable with one that has a capacitor in it. Fusion owners with the no-start/intermittent start issue can go to their dealers with the TSB. I have tried to write down some simple tips that may help you to find out why
your car won't start. These tips may also prevent you from being overcharged by
dishonest mechanics - you will often be charged more at a garage if you look
unfamiliar with the car mechanical aspects.
It's frustrating when your car
won't start - this happened at least once to most of the drivers. I had
situations when my car won't start many times. But no need to panic. The process
that goes on since the moment you took the keys out of your pocket to the point
where the engine is running is a fairly simple one and it involves few steps.
The engine computer uses the signals from the crankshaft and camshaft position sensors to know which cylinder is in the compression cycle. If either of the sensors is bad, the car won't start. Similarly, if the timing belt, chain or gears are broken, the camshaft won't turn and the engine won't start
The fuel pump starts running, building up the fuel pressure in the fuel injector rail. The engine computer alternatively opens electronic fuel injectors that spray short bursts of gasoline vapors into the intake manifold (or in case of the direct injection, straight into the cylinders). If the fuel pump is bad, the car won't start.

Sounds like it may be the spark plugs. If you have a spark maybe a fuel filter is clogged? Hope all goes well!

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"
