The HPFP is run by mechanical means of camshaft turning with motor running. It is a mechanical pump with the shaft moving by mechanical hook up to camshaft with the shaft of the pump sealed. There is no Computer running HPFP. U are abeing dupped. It is a common leak for mechanical HP fuel pumps. Most likely there is damage to your motor from running so much gasoline in the oil already. If that is the case the rings are damaged and your compression is less than required in specs.

This just seems to go on and on. Research GDI pressure pumps on U tube. It explains the ECU's part in turning on the solenoid valve at the HPSP for the injection event lasting mili seconds an the mechanical operation of the piston pump inside it.

I guess I don't need to worry about whether or not the test was or even could be performed because they are going to replace the pump.

Awesome as that is the easiest and most obvious. Hope as all else seems so bad for you. Think about the disgusting out comes of a new short block an same fuel system with negative results.

Well, I hoped it would solve the issue.....
The results form the last oil change show that it had 5% fuel dilution on oil with 2,000 miles on it AND the new HPFP has made no difference. I am above the full mark by 1/2 inch again after about 400 miles. I am next going to push for all the injectors to be replaced, even though they supposedly determined that they weren't leaking.
