I am in dire need of assistance. I have a 6.0 that I originally thought had the starter go out on me so what do I do, go buy a starter and replace it. Well no luck there so I figure that my ignition switch is bad. That's not it. So I do what everyone's first step is and check my fuses and relays. Nope not it, everything checks out good. Battery is good, plugs and wires are all good fuel pump and filter are great.... Should I be worried it's my BCM??

 

Does it crank?

 

Check all your fuses and swap the relay my 02 does the same crap when I blow a fuse not sure what one it is though

 

 

My dash lights lit up when turning the key but wouldn't crank. Solution was the Starter relay in the under hood fuse box. Easy test is to pull it and replace with the Park LP relay which is beside it. These are the same relay.
