Basically I'm just requesting any tips as far as greasing or lubing anything; or any other important factors I should take care of while I do the install. Also I live in covina so if anybody wants to have a jeep meet or even help me out with my install I would appreciate it. Thanks jeepers, after two years I'm excited to finally give my jeep some love!
Should look pretty good after you get that all on. Make sure you center the steering wheel to keep the ESP light at bay

Ok so it didn't really spike up all that much just 5 PSI?

Ok cool. What was the pressure with the vacuum off of the FPR? Curious now because you know you can get the pressure up, you know the vacuum to the FPR is good, btw how much vacuum does it have? You know the seal is good in the FPR, I wonder if the spring is going bad. Like it's weak now and not giving enough resistance to push past the vacuum. Does that make sense? I can really word stuff to well I'm more of a draw it out to explain it kind if person lol

Two thing control fuel pressure, well three really. Pump provides flow then a relief valve that is set at 46psi most built into the filter if the filter has 3 connectors not sure what's on the Cherokee and of course the injectors but the injectors can't really cause a major drop in fuel pressure and still have any ability to cause a useable combustion, So that's eliminated.

that would be awesome! I was just about to go at taking the fuel pump out when I heard my phone. I will try this suggestion first. Thank you.

I would look for a vacuum leak.

On my JK actually, just a couple weeks after the battery warranty ran out. Hard start, rough idle, stalled and gave me an engine code. Have you checked the injectors when you started on the fuel system? I might have missed you saying that also. Whatever it ends up being you'll have to let us know! Good luck.

I'm wondering if the solenoids in the injectors are sticking at times. You can take them out, put some sort of solvent (no brake cleaner) on the fuel rail side then power the injector off a battery and make sure they fire correctly.
