Be sure you have checked the impact safety switch. Your owner's manuual should tell you where it is if it has one. This switch kills the power to the fuel pump after impact. It has a push button reset. Check for voltage at fuel pump to rule out having to change the pump again.

from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.
1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..
2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)
