fuel problems
I have a 1992 jeep cherokee laredo with fuel supply porb I believe.
It will start put die quickly unless I rev it up with gas pedal.Put new fuel pump and filter in, now will idle but not smoothly. Have no codes showing up. I thought was fuel pump because made odd nose in tank one day when starting but ran fine that day, the next day is when it wouldnt stay running, is there a pressure regulator that maybe causing my problem. I have 25 psi at rail now.

25 psi is low,should be approx 30-35 running and approx 40lbs when you unplug the vacuum to it,the regulator is located at the end of the fuel rail next to the schrader valve where you checked the pressure.
