Ok I was driving home today and turn on to my street and then I lost all power my engine was still running but it was super rough idle and it would drive but hardly any respons to the gas. I could maybe go 10 mph. So stopped got out and looked under the hood and the only thing that looked out of place was this



But I have no clue if that is anything or not. Any ideas? Thanks for any help

P.s It is a 2006 4.6

 

I'm no mechanic but it could be the fuel pump driver module. They're known to go bad on these trucks and that sounds like the symptoms of that problem.

 

That's the little black box under the spare tire right? Sorry I don't know a whole lot about this kind of stuff

 

You are correct. If it looks all corroded or broken then that might be your problem.
