Again, use the whole information, not just a piece of it. I posted it previously which Shiv, again, provided a link. I find it very disappointing that you would post about someone else’s situation prior to them making a full diagnosis. I was out of town and had no way to fully investigate until I got home. When I did, I determined it was most likely a loose connection in the harness which was exacerbated by the cold weather overnight.
I will be testing everything in full, in a correct manner, while understanding what I am dealing with over the weekend. And only then a proclamation should be made.
Lastly, a HPFP is not going to fail due to boost. I would expect any basic wrencher to understand this. The differential pressure and increased load on the injectors, and subsequent load on the pump amounts to about 0.3% change. I know they are delicate, but not that delicate.
