1996 Jeep Cherokee, straight 6cyl, new fuel pump and now it is struggling running and pushing to much fuel. How do check fuel regulator, or where is it located? Thanks

Hi, the likely problem is a worn out CV joint on one of your axles. Check for a torn boot on either axle. Once a toot tears open, dirt gets in and wears out the joint. Please let me know if you have more questions, and thanks for using FixYa.

your pcv valve might be plugged check to see if it rattles

Check the in line fuel filter, could be under hood or along frame. Also there is a screen in the tank but should have been checked when fuel pump was changed.....

CHECK FUEL REGULATOR ON FUEL INJECTOR RAIL,&ALSO FUEL PUMP, CHARLIE

change the auto choke temperature sensor

You meant the fuel pressure regulator? It is located on the fuel rail and has vacuum attached to it. This is not the problem with your car tho. Check the ignition module, and the ignition coil.

does your jeep run rough? idle is real low? and when you are driving and push the gas hard it doesnt want to move? if so it is most likely the mass air flow sensor. i had to replace that 2 or 3 times on my 1999 jeep cherokee

I believe you are on the right track. E.C.U. or relay.

Also check the vaccum hose from the fuel pressure regulator to the intake manifold, it is right on top, to the front right of the valve cover where the fuel lines attach to the fuel rail, there is a small vaccum hose that runs from the regulator to the intake manifold, I have a 93 grand cherokee limited w/ 4.0L 6cyl, it was hard to start at times, wouldnt start at times without starting fluid spray and had your symptoms at idle, running rough like it wanted to stall like it was out of gas, I had various opinions ranging from fuel pump was bad to the fuel filter to the fuel presure regulator, the fuel pump relay ,etc....after replacing the relay and having the same symptoms, some digging brought me to this vaccum hose, wich had a break in it, when it was replaced it allowed the regulator to have the correct fuel pressure output and solved all the afforementioned problems way cheaper than the suggested alternitives. good luck.
