About a week and a half ago I was driving and my truck surged, similar to when it de-fuels before a shift I was going about 30 mph. Got to my destination down the street turned of the truck all was normal. About 30 min later started normal drove about a mile then I got into the throttle a little bit and it just shut off. Made sure it was primed then cranked it several times and it started with throttle, but turned off when I let off. Couldn't start it again so my dad brought me a filter changed that still no start called AAA. After reading the forums and from my experience with other motors it seemed like a fuel issue so I changed out the FPR. On the 4th or 5th time cranking it started for a few seconds then died when I let off. My buddy with efi live came over and said I have plenty of rail pressure but that my crank position sensor was not counting so I changed that out. Still won't start and I do not know where to go from here.

If there is a trusty mechanic in Phoenix AZ that could help I can pay. I have some people counting on me for a trip this Friday 3/9 hopefully I can get this fixed.
