I recently bought a 09 duramax with a fass 165 pump on it. I changed the filters on it today and didnt prime them. I turned the truck on which lasted for about 20 seconds now it wont crank over and the Fass pump wont turn on. The fuse is good on it. Any suggestions?

Fixed. It was the relay, it was corroded and from what im guessing is that with it not being primed it was trying to suck more and thats when the relay gave out.
