new member with p0088

Hi guys i'm new here! lately I've been having problems with my 08 f550
I have a p0088 and I know it's associated with the HPFP, and there is a tsb for a reflash. Well the reflash was done already, and yet I still have this code and it goes into limp mode while driving heavily. I replaced the frp sensor, was hoping it would fix it but it didn't. is there any TEST I can do to condemn the hpfp? I don't want to just throw a pump in there as it's not in warranty anymore.

any help would be appreciated! thanks guys

You'd have to get the Fuel Rail pressure. I dunno what the expected pressure is, but mine is 32k PSI(according to my Droid). You could also look at the Fuel filter. If that's filled up, it could have low fuel to the pump, or a plugged filter up top preventing fuel from reaching the rail.
