Have new fuel pump and new fuel filter, and when it starts it runs fine but sometimes it seems like the fuel pump is out and wont start lately its been hard starting

Due to the age of your jeep, You need to replace the fuel pump and filter along with replacing the water pump and thermostat as well as coolant temp sensor. Fuel supply and coolant flow and temp sensing is critical to Cold start (open loop) and warm up (closed loop) Idle function and fuel mapping. Change the air filter too.

sounds like she jumped her timing..might be a mechanic job....sorry

The fuel filter could be plugged.

is the fuel pump extremely loud? i've dealt with a few of these, and although the driving symptoms differed, a new fuel pump fixed a great majority of them when the pump was whining.

How did you determine its not the fuel pump?It could be the fuel filter but I dont think so.Your truck requires a certain amount of fuel pressure to start and a different amount to run properly.You would have to check what your fuel pressure is to say its not the pump.It should be something like 65 psi to start and 55psi to run.Even though you can hear the pump come on when turn the key it might not be putting out enough pressure to start the truck.I realize im a little late with this post but it might helpfull to others.

this year model is notorious for fuel related probs...check the remainder of the fuel system, injectors, and the fuel pressure regulator also verify that the fuel pump is actually running and getting the correct amount of power to the pump itself..... it may not be bad just not getting enough power

Replace the fuel filter before the pump goes bad, just paid $700 to replace OEM withan aftermarket fuel pump and filter (better than $900 quoted by another shop. Had I changed the filter sooner, may have avoided. Now dealing with a bad intake mfld gsked and old leaking oil cooler lines. Help, GM is killing me!! These vehicles are notorious for various issues.

Good luck

I realise you have probably solved this problem by now so sorry for the late news mate . Had a similar prob and it turned out to be an alternator malfunction . I replace the brushes and off she went . These things send voltage from the alt . to a fuel pump relay or whatever so the pump wont run if the eng isn't (or the alt isn't outputting any voltage.) . Hope you already had it sorted . But I hope this helps if not . Cheers Simon .

that could be your starter

Fuel pump is most likely the cause. Probably just barely making the required pressure to start. Needs to maintain 60-66 psi while cranking to start.
