How do you go about correcting fuel pressure? My Jeep hesitates when climbing hills and hesitates when trying to accelerate. It slowly speeds up but over more time then it should take, it does not have the power it once did to get up & go. Does not have the take off power to get out there when needed. when gets to around 70 then and only then it feels normal and wants to take off. Again it also takes time to get to 70/ where as at one point a week or so ago in third would take off like nobody's business for a 4 banger on a hill!/ some thought I had a six ! now? I am lucky if I can hold 55 going up with no power for passing .
I don't think it's your fuel pump have you tried changing your plugs or doing a full tune up had someone that had similar problem changed plugs wires and cap and rotor and it runs great now even these newer cars need maintenance. Oh and the cleaners you are putting in your gas are just alcohol same thing that's 10% of your gas don't waste your money many studies have been done and have found them useless.

so you just said to me it BOG up hills and does not really catch up, really catch up means 100% full factory 2.5L power up hills, so that might be (bad map readings or IAT or low fuel pressure) i see you have posts for many cars are you learning car repair? all mechs, own a fuel pressure guage.and know how to use it the 6 ways in the FSM book, the the tests are, cranking pressure, ? running pressure, leak down test (see if injectors leak) fuel pressure reg tests and a battery of inejector balance tests to find weak or even bad injectors) this all must work right or it will bog. all MPI engine do that. ALL.
btw 2, here is the FSM , for your car, FREE !

i flubbed up the paster buffer.
is the CEL lamp on , driving??????????????????????
did you scan the PCM with any scan tool?
fixing modern car with no scan tool , is like driving blind folded.
if you cant see the sensors, you are blind, for sure.
i fix old pre OBD2 cars callled OBD1 cars. but have every meter on earth and data loggers to find true cause on them....
a good scan tool costs about 2 hours shop labor.. so.......IS AND INVESTMENT GRADE device, has payback, and yield. and well , is free, (math)
pays back in wasted labor, and guessed at parts, and more. down time, etc, etc.
