Vehicle turns over but will not start ,I reset the fuel shutoff swiutch but didn't help

From your owners manual, the shutoff is not a manual button:
Roadside Emergencies
FUEL SHUTOFF
WARNING: If your vehicle has been involved in a crash, have the fuel system checked. Failure to follow this instruction could result in fire, personal injury or *****.
In the event of a moderate to severe collision, this vehicle includes a fuel pump shutoff feature that stops the flow of fuel to the engine. Not every impact will cause a shutoff.
Should your vehicle shut off after a collision, you may restart your vehicle. For vehicles equipped with a key system:

1. Switch off the ignition.
2. Switch to start position.
3. Switch off the ignition.
4. Switch on the ignition to re-enable the fuel pump.

For vehicles equipped with a push button start system:

1. Press the START/STOP button to switch off the ignition.
2. Press the brake pedal and press the START/STOP button to switch on the ignition.
3. Remove your foot from the brake pedal and press the START/STOP button to switch off the ignition.
4. You can either attempt to start the engine by pressing the brake pedal and the START/STOP button, or switch on the ignition only by pressing the START/STOP button without pressing the brake pedal. Both ways re-enable the fuel system.

Note: When you try to restart your vehicle after a fuel shutoff, the vehicle makes sure that various systems are safe to restart.Once your vehicle determines that the systems are safe, then the vehicle will allow you to restart.
Note: In the event that your vehicle does not restart after your third attempt, contact an authorized dealer. 2015 Edge Owner's Manual

I don't think this vehicle is equipped with a fuel/inertia cut of switch. If there is one, your owners manual will give the location and reset procedure

• The inertia fuel shutoff switch is located behind the driver side scuff panel. An access hole is in the scuff panel to access and reset the fuel shutoff switch.

NOTE: In the reset position, the button can be pressed an additional 1.59 mm (0.0625 inch) against a spring. This is a normal condition.
To reset the inertia fuel shutoff switch , press button on top of inertia fuel shutoff switch .

Hey Carlos , does your vehicle run ?
Fuel Reset
The FUEL RESET indicator is grounded through the inertia switch whenever the vehicle is subjected to a high force situation. The inertia fuel shutoff switch (IFS switch) (9341) cuts off the fuel pump motor. The FUEL RESET indicator illuminates when the IFS switch has been tripped.

I think before I started guessing, I'd go to one of the bigger parts stores where they will scan for fault codes free of charge, and see if any come up. I'm guessing no check engine lights are coming on, seeing how you didn't mention it, but may be a chance scanner will find something. The other thing I would do if no codes are coming up, is to have fuel pressure tested, which should only take a few minutes, just to confirm that your fuel pump is holding proper pressure when vehicle is warmed up. Not uncommon for them to work good when first started and they are cool, but start to act up and lose pressure when they get heated up from running for a while.

Try A SMALL SHOT Of Starting Fluid Sprayed into the Snorkel
Intake @ Air filter. If it Starts and Does NOT Run After Burning Starting Fluid the Fuel Pump Has Failed. (My Personal Hunch) is (FUEL PUMP FAILURE) BE SURE TO ELIMINATE THE INERCIA SWITCH< it is a fuel shut off switch >>>>> WARNING: Do not reset the inertia switch button if you see or smell fuel.

1. Turn ignition switch to OFF.
2. Check for leaking fuel in the engine compartment, fuel lines and fuel tank.
3. If no fuel is apparent, reset the inertia fuel shutoff switch by pushing the reset button on top of switch.
4. Turn ignition switch to START for a few seconds, then to OFF.
5. Again, check for leaking fuel.

LOCATION

1. Open luggage compartment door.
2. Remove two screws retaining inertia fuel shutoff switch.
3. Disconnect wiring harness connector from inertia fuel shutoff switch and remove inertia fuel shutoff switch.
4. To install, reverse removal procedure.

FUEL PUMP SHUT-OFF SWITCH

After a collision, if the engine cranks but does not start, the fuel pump shutoff switch may have been activated. The shutoff switch is a device intended to stop the electric fuel pump when your vehicle has been involved in a substantial jolt.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, remove the cover plug in the trim and reset the fuel pump shutoff switch by pushing in the button on the switch.
4. Turn the ignition to the ON/RUN position. Pause for a few seconds and return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

The fuel pump shutoff switch is located in the passenger's foot well, behind the kick panel. The reset button is accessible through the recess in the kick panel.

Replace the cover plug in trim after reset procedure.



THis and other details can find in the Owners Manual.

Hope helps (remember rated and comment this).

Can I see photos

If the Engine Cranks but Does Not Start or Does Not Start After a Collision Fuel Pump Shut-off Switch if the engine cranks but does not start or does not start after a collision, the fuel pump shut-off switch may have been triggered. The shut-off switch is a device intended to stop the fuel pump when your vehicle has been involved in a substantial jolt.

Once the shut-off switch is triggered, you must reset the switch by hand before you can start your vehicle. The switch is on the left side of the trunk...

1. The electrical circuit of the Inertia Fuel Shutoff (IFS) switch may vary per engine/vehicle application.

Fuel Pump Circuit Operation When the ignition is switched to the ON position, it turns the EEC Power Relay on. The EEC Power Relay provides power to the EEC-IV processor and the control side of the fuel pump relay. Power for the fuel pump is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flow is through the fuel pump relay and Inertia Fuel Shutoff (IFS) switch to the fuel pump. The IFS switch is a safety device used to shut off the fuel pump in the event of a collision. If the IFS switch is "tripped," it must be reset by depressing the white or red button on the top of the switch. The fuel pump relay is controlled by the Powertrain Control Module (PCM).
When the ignition switch is turned to the ON position, the fuel pump will operate. If the ignition switch is not turned to the START position, the PCM will shut the fuel pump off after approximately one second. The PCM will operate the fuel pump when the ignition is in the START position to provide fuel while cranking.
After the engine starts, the PCM will continue to operate the fuel pump unless the engine stops, engine speed drops below 120 rpm, or the IFS switch is "tripped."

System Diagnosis Note: Grounding the FP lead at the DLC will allow the pump to run continuously with the ignition switch on.
