Truck isn’t starting

So I bought a 87 ford f250 xlt lariat with a 7.5l 460 gas engine. When I bought the truck and turned the key lights on the dashboard appeared, the battery light and another light on the right. All it did was crank. Then all of a sudden the lights are not appearing. On top of that the fuel pump isn’t getting power, and the spark plugs. But it was still cranking. I thought it was just bad fuses so I replaced them but nothing. I shot the wires with a multimeter and still nothing. I made sure the solenoid was working at it was. The fuses for the door lock still work but not the fuses for anything else. I’m at a loss and need help, I don’t know what wire that could’ve gone bad but anything helps. Thank you

Forgot to mention, the ignition switch was moved to a different spot, so I have to turn the key and push the button
