2005 scion xb won't start please help!!
 

Hey guys I'm new to this page and new to the scion life. Well I have a 2005 xb. This morning I went to start it up, it cranks over but fuel pump don't turn on and from what I know of its not getting spark. The check engine light is not on. I drove it yestaday and it ran perfectly fine. Last night when I pulled it in the garage I had to fix the wire to the horn behind the bumper. It came disconnected. So I had to splice it together. I don't think that would have anything to do with it tho?! And then I blew out the fuse box under the hood with the air hose. Other then that nothing was done. I tried to hook the odb scan tool up too see if any codes popped up even tho the check engine light wasn't on and it wouldn't connect. All fuses are good. I'm stumped! No idea Wats going on. Can it be the ecm. Or does the crank position sensor control that stuff?! Any info will help at this point. Thanks guys.
