I wreaked my jeep last week anyways, they delivered it to me yesterday it cranked I shut it off aft er a few seconds. Today I tried to start it won't do anything I can squirt some gas in the intake it will run for a few. I've checked all the fuses and swaped the relays. What am I missing? The rail has no fuel in it, is it possible for the fuel pump to be bad?
 
Could be an inertia(spelling?) switch. Cuts power to fuel pump when in a wreck I think. I have no experience with one of these but I'm pretty sure most newer vehicles have one.
 
I would start simple, first check the fuel pump. 1-Turn the key, dont crank and see if you hear it. Do you hear it? If yes then go to step 2 no i would start by replacing it. 2-Check Fuel filter make sure fuel is coming out and no hoses got pinched or snapped. 3- some jeeps uses what is called a fuel pressure regulator. ( this allows fuel to enter the fuel rail) These can go bad VERY easily and its possible this is it. Check those and come back and tell us whats up.

Before you drop a bunch of money on a new fuel pump, make sure it's actually getting 12v when the ignition is switched to "run".
