I am completely frustrated with my F550 V10, it cranks forever with no starting. Has been doing it for 2 years. Multiple mechanics looked at it, with no results. I replaced a few parts, all to no avail. Have seen a lot of internet suggestions, some of which I lack the skills to do and it's too big being a shuttle bus to tow anywhere.

I need a most excellent auto repair person, ideally a Ford guy in DC / NoVA area with strong diagnostic skills who can look at it and just take it from point A to point B which is defined as the working condition.
