Having done this once on my old van I can give you a few tips you have not done. It was NEVER found at a dealer what the REAL problem was but what we did fixed it so to speak.
First off the fuel recirculator next to the fuel tank that has 4 hoses on it should go be replaced next is the fuel filter and then there is the fuel pump in the tank that may not be working just right and then there is the hi pressure pump that could be at fault
as could the fuel reley
Check all of this and then see what happens.
God luck there I hada hell of a problem with this one!
