Starting Problem

I have a 1994 Ford Ranger with the 4.0 motor and it has 130000miles. Today I was driving and hit a bump, the truck shut off and I can't get it to crank. I noticed when I turn the switch on the fuel pump does not come on. I replaced the fuel pump breaker switch and that did not work. I checked the inertia switch and it has not popped. I can jump the green/yellow wire under the breaker and the fuel pump will come on, but it will stay on not just come on for a few seconds and then go off. I can prime the fuel rail by doing that and then I can connect the black/yellow and the red wires together and the truck will crank long enough to run the fuel out of the rail and then it will shut off. I think what I am doing is jumping the ignition switch, but I am not sure. Do you have any idea what I should do
