I have a 98 cherokee classic lately its been bogging down when I push it to the floor. I checked the fuel pressure today and found that whith the key turned on but not cranking the motor I get 33 psi, when i start it and let it idle the fuel pressure drops to 31psi, and when i go to wide open throttle it drops down to 28 psi. I don't think these are good readings.
My question's are does my jeep have a fuel pressure regulator, and does it sound like the fuel pump needs changed? Thanks for any advice
