ANY 05 JEEP G.CHEROKEE MECHANICS

Check all of your electrical connections to the pump first. Also check the fuel pressure reading when it IS running to see if it's within specs. (It will help a lot if you have a factory service manual, or access to specs) Make sure it has a GOOD ground. It may be the pump is going bad too! If you do need to replace the pump, spend the money & get a good one. (Carter, Delphi, Etc.) Don't get a cheaper one like an Airtex or anything like that, they just don't last & it's a lot of work to replace them, because they are in the tank. Check ALL your connections FIRST.
