Okay so it all started with installing a lift pump (raptor 100) truck ran for about 15 seconds and died. Pump would not turn on so everyone told me to jump the relay with some wire and if the pump turned on i need a new relay so i jumped it and the only thing that happend is now when it turn the key on the asd relay goes freaking nuts buzzing its head off . Long story short i got a bad pump so i took it back and got a new one. Now every once in a while when i go to start my truck i turn the key on and the relay goes crazy and truck wont start but if figured out if i open the hood and hit the fuse box a couple times the relay stops, the pump turns on and the truck will start and die/ or sometimes start and stay running. Then ill go to start it again later it will start and then try again and get just the buzzing relay hit the box the truck will start. So im pretty lost on whats going on but it sounds to me like a ground somewhere but i have checked every one i can find. And also when the key is on if the relay is buzzing i get a no bus code on the dash. I am really stumped on what is going on and scared to drive it anywhere with the thought of it dying and i dont have they money to pay 97 dollars an hour for the dealer to look at it so any help would be greatly appreciated
