1) When you are replacing parts, are you using genuine OEM parts from a dealer or are you sourcing them from Amazon or eBay or some other online store? I ask this because the existance of counterfeit parts are at an all time high right now.
2) Have you checked your bypass valve operation? Before installing my Harrop, I had to work the bellows in and out several times as it was sticking. And this was a brand new unit directly from the factory.
3) Have you tried reflashing your ECU with the most current revision from your tuner?
4) Who is your tuner? |
Currently right now.. all OEMs! except from the used HPFP which is still sourced from a relatively low mileage donor.. though the issue didn't change.so That's pretty much crossed out.
Yes. Bypass seems fine. This is a recent issue. I've had the harrop installed for few years now - never this particular issue.
I've reflashed different tune from my tuner..going all the way to the base one ..It didn't matter.
Tuner is Mike from Xer-Limit.
i'm going to be doing a fuel pressure test (among other stuff later today).. I have a feeling there is a leak between the low fuel pump to the fuel rail, and the issue exacerbates as temp rises which means leaky line soften my high temp? Oh god that sounds really terrible.
I do kinda smell fuel though (which i completely forgot to mention)
Thak everyone for the continued great input. I will log alot more data today.. idling and cruising.
