is there a risk of damaging it? is there smt special about redline specifically?

Okay got it but my question is can I use any fuel system cleaner as lube instead of redline?

Enki I’ll take my pump back out and clean it but I don’t see how that’s gna fix it. can I use a generic fuel system cleaner for lubing it or does it need to be redline, I don’t have it locally I’d have to order online. also I get the pump is a positive displacement pump but doesn’t Low side...

I don’t know good point, honestly if I can avoid taking the pump out of the car that’s be great because it’s snowing where I’m at and I gotta work outside now. The pumps in and it’s lubed and I inspected it there’s no damage. The problem is there’s a whistle noise ever since I changed the fuel...

Why does the manual say 55-70 psi then?

Can I not take it off separate from the pump, I can't take the pump out again its cold asf outside I got to put it in my moms garage the last time but she's fed up of me being in there I get 36psi koeo

I read its best to take the spill valve off while attached to the car which is what im planning on doing, I bought a bottle of injector cleaner but its not redline, should i dump the bottle in there when the spill valve is out? The issue seems to be low ITFP tho

Its not dexos oil, as for the pump I just cleaned it and re lubed, what would be the point in doing it again?

5w-40 pennzoil euro, 91 octane (never used anything else and there's no E anywhere near me that a PO might have used), non chlorinated break cleaner to clean, oil to lube it, nothing was sticky, and for the spill valve im waiting to get my hands on a 32mm wrench but I plan on doing that this...

So I was hoping that id make one last post on this thread saying the issues solved but nope Heres what i did, took apart the fuel pump internal everything looked good no scratching or scuffing. re lubed everything and put it back in the car with 3 new bolts. I got a known good PRV from chris...

you seem to be focused on it being something to do with fuel pressure, lean at idle and then is fine under load sounds like a vacuum leak

+ltft usually means vacuum leak, are you stock or what mods?

i posted in your thread i think that the puns solved my problem, I think it was synthetic atmosphere that sent me the link

Just realized I never posted an answer to this thread, the pins on injector 2 weren't seating in the connector properly i straightened them out and code went away

Here’s a better video away from the bov for you guys, when I was checking w the screw driver it seems way louder when I check at the fprv then at the fuel pump

So new issue now, hpfp is making a squeal/ metal on metal noise under load. So cold started the car and went under the hood and it’s coming from the hpfp area. I’ll attach a video.

new fuel pressure sensor solved my 0psi issue, here's the part number i used 0261545038. Now i just have this rattle/whistle when accelerating but at least it drives properly now EDIT: DONT GET THAT SENSOR its garbage doesn't read past 1420 psi and caused some whistle noise to happen, i just...

Im getting p0192 and p0192, fuel pressure is still 0 at all times but it runs, wants to die if I try and spike the throttle. I think I should check the V reference but im not really sure how and could use some help, thanks guys Edit: Checked the yellow signal wire on KOEO and i had 1.8-1.9...

Check the continuity of the wire from one end to the other, it might be frayed or smt look over the whole wire. im having a fuel issue too lol

So I went through a diagnostic procedure for p0192 for speeds and I found that 2 wires are shorted to each other because I get resistance between B and A when they shouldn't be connected anywhere. So I guess this means I need to take out the harness and take a look for corrosion or tears EDIT...
