Final update: I believe we’ve fixed the issue. I’m going to be doing some logging tomorrow to be sure. I bought a fuel rail/PRV/Pressure sensor...
Should I be wanting to see around 1850 then? Isn’t that the crack pressure for these? Is there such thing as an upgraded RV?
Update: swapped a different hpfp(confirmed working) assembly into it and same issue. KOEO test built pressure up to around 1300psi and a bad RV...
Checked my hpfp, made sure everything was seated correctly, looks clean inside, no damage anywhere. Swapped in my old RV and things got slightly...
Yeah he’s just flaky and busy with work and school. Gonna take a look at my hpfp and do what Enki suggested. After replacing the seals and...
Thanks for the part suggestion. Replacing it with that part worked, for the most part. Now I can get into boost, though my fuel pressure doesn’t...
Correct. Cheapest rail I could find was $90 so I bought a used sensor from a partout. Do you mind posting the part number for the sensor you’re using?
I wouldn't say I'm experienced.. but I felt like it was pretty straightforward. Watched some YT vids on tear downs, cleaning, and followed...
Rail pressure is only normal at idle after the car has warmed up. During cold start, never goes above 1000~ and while cruising/WOT never above...
So I teed up a gauge to my itfp today after work and while the key is ON, it's holding pressure at 60~psi so I don't think the pump or regulator...
I’ll give it a good push and see. Hmm alright. I’ll swap the new sensor back in and look into getting another pump and regulator. I tried...
Ok that makes sense. So with the new sensor, I see 33psi with the key in the ON position and normal idle pressures, but nothing over 1000~psi....
Right. I just don’t think my itfp is my issue at this point. I believe it’s related to a wiring harness or my spill valve. Gonna see if a buddy of...
What was your fix? Replace the sensor or rail? That seems to be exactly what I’m seeing. I’ve also read that a faulty spill valve can cause stuff...
That’s what I was thinking. Thanks for the link, I’ll save that for now. I need to tee a gauge to the tank and get a more accurate reading before...
