so i have a 2001 f250 and it refuses to start. i tried a new started solenoid and a new started switch thats right beneath the steering column by the fuse panel, checked to see if any wires are cut or disconnected and everything is fine. it just wont start by key. if i turn the key then nothing happens(wont crank at all) but if i touch a piece of metal across the solenoid then it starts right up and runs fine. cant figure this one out. so now also my hubs rattle like crazy, i heard this is pretty common but wether the front hubs are locked or unlocked, it still rattled. what do i need to replace to fix the 2 issues?

 

update: found two 7.5 amp fuses blown on the engine compartment fuse panel, also found a 20 amp blown fuse. could be my starting problem?
