So replaced injectors, started up without the driver side injector cover. PRETTY sure I can isolate the noise to the DI pump using my stethoscope.
When revving noise appears to disappear? Going to take it for a short drive tomorrow/friday and see how it is edit: Sounds EXACTLY like this, with a VERY similar cadence https://www.skyroadster.com/threads/...jectors.97189/ also no codes

Think I can just replace the hpfp if so? Maybe bad gas? Has been sitting for close to a month

![]() edit: I mean "fuel system status" codes. I don't know how it would be possible for yours to be in fuel-cut mode so I'm not really sure what any of it, including my own, means. ![]()

I drove today and it seems mostly okay? No codes. Didn't get super into it since it's base tune. Clicking seems to have decreased drastically so not sure what it was but it definitely still seems present, just not nearly as loud. I did order a new HPFP off of ebay from a 19' with 15k miles. Sent logs to tuner so we will see what he says. Also have a super slow leak from the area in green unfortunately. Tried tightening but no luck. Going to try an Earl's 10an seal and some permatex high temp thread sealant IDK this oil drain location is honestly not my favorite due to proximity to header and belts (it is not touching manifold, it's the angle of the photo. It is close at it's closest though at probably 1/4-1/2 of an inch)

It's clearly having trouble regulating rail pressure. If you enable the PI ratio graph you can see that your keeps trying to kick in but flops. That might even be the sound we hear.

See youtube video for clicking Then see that fuel system status fluctuates between 2 and 4 and di fuel pressure seems to be very inconsistent OEM injectors, di injectors recently cleaned. 3 bar omni map. K00c tune.

Yes seems strange usually di fuel pressure failry steady 3 to 4 MPa at idle Check the grounds on the DI computer under Bonnett all three bolts in and tight Also it might be the di fuel pressure sensor feeding the di computer weird info then the di pump tries to follow that. My guess would be di pump or di pressure sensor if the di computer is correctly earthed/grounded unless there is something very weird in tune |
