Is the Inertia switch and the fuel pump relay the same thing?

No. The relay powers up the fuel pump and the inertia switch kills power to the fuel pump in the event of a collision to prevent a fuel related fire.

2010 nissan versa got in a collision. Wont crank over. Would the fuel inertia switch cause this?

Fuel inertia switch stops the fuel pump running in the case of a collision causing a broken fuel pipe which otherwise could spray a litre of petrol every few seconds and rather spoil someone's day.

Certainly a tripped inertia switch would prevent the engine from starting but I doubt it would stop the engine cranking, though I don't have up to date information on the model and there could be different safety regulations where you are.
The inertia switches are accessible and resettable so why not just reset it and try again. Your vehicle handbook will have the details.

An immobiliser stops the the engine cranking on some vehicles as well as stopping the spark and injection and often the fuel pump.
Bridging the battery positive wire to the solenoid to make the starter crank the engine won't be switching the rest of the stuff back on.

Cranks but wont start

This problem can be from the Inertia sensor. On Lincolns, the Inertia switch is usually close to the Air-ride cut-off switch in the trunk. Or behind a front floor kick panel.

There is a reset button on the switch. Check photos on the Web if you want to see what you are looking for.

Fuel pump reset switch

This switch would be located in one or two places. If you have Air-ride suspension the Inertia switch is usually close to the Air-ride switch. Sometimes there is a plastic cover over the switch in the rear cargo area. The rest of the time the Inertia switch is in front by the front seat kick panels.

There is a reset button on the switch, just press and hold for a second or two and the reset is made.

It got wrecked and i fix it but it wont start

Did you check for an inertia switch. Most vehicles have an inertia switch installed in the fuel pump circuit that cuts off the fuel pump when involved in an accident.

Explorer wont start

You need to tell us if it will crank or not. The most common cause for not cranking is the interlock system on top of the brake pedal lever. Go under the dash and you will see a switch which often gets moved or broken by drivers' feet.

If the engine cranks, then you need to determine if it is a gas or spark problem. Sometimes you can use Starting fluid sprayed sparingly in the air intake and then try to start the motor. If it tries to run, you have found out that you have a fuel problem. If it does not try to hit or run, it is likely a spark problem.

When you reach a no start condition, often a trouble Code is in the computer. A scanner will quickly indicate many possible problems and eliminate guessing by displaying the correct trouble Code.

There is also an inertia sensor that is usually around a kickpanel. Browse the Web for a photo. This switch will activate sometimes with a doorslam or cargo lid slam. It is meant to be reset and then your fuelpump will work. Sometimes the inertia switch is in a rear cargo panel. Browse the web for a diagram titled, "fuel inertia switch", for your vehicle.
