Electrical help! Fuel pumps won't come on, fuel pump relay makes clicking noise
 

91 f150 2wd dual tanks. The other day I jumped my truck, but I have a negative terminal shut off switch and didn't turn it on all.the way when jumping it and it fired through my solenoid and the wires that go to my alternator caught on fire. I replaced the solenoid, replaced the chunk of wiring that was burnt. And my engine wants to start, it just cranks over and over, sometimes it will fire up for about 1 second but that's it. So I have been trouble shooting and my fuel pumps don't seem to turn on, and the fuel pump relay clicks and makes a noise. Any help or advice?
