need more info..

Does it have enough fuel in the tank??--it could be a lot of different things,or a combination of more than one..if it was real cold (under 20 degrees) the fuel might have gelled up,and clogged the fuel filter--or it could be dirty and plugged..the fuel shutoff solenoid might have came unplugged,and the power wire on the injector pump might have come off or lost power--look at the big pink wire on the injector pump and make sure it is still connected,same with the green wires near it,and check with a test light with the key "on" to see if power is getting to both wires--if not you might have a blown fuse or have bad wires--

If you have power there,it could be the fuel shutoff solenoid died--but a bunch of other fuel related problems can cause the same symptoms--one is a cracked or leaky fuel line or rubber hose letting air into the fuel system,causing an air lock--it wont run on air.another possibility is a plugged return line on the injector pump..you need to do some investigating!.
