High pressure fuel pump
Okay so I think my HPFP is going. The shop that tuned my car said the same thing, but they do no specialize in Solstices and I am not an expert by any means.
It is making a whining sound that starts once the cars engine gets closer to normal operating temp. It is constant, it goes when it is idleing and when it is under boost.
I am wondering if anyone else has had this issue. If so does these seem like it is the HPFP or something else? I called my local stealership and they said the part is like 700 hundred bucks which is really crap IMO. I heard they are the only one that sell the part though so I guess I will be forced to pay for it.
Any help is appreciated guys, ty in advance
