1996 JEEP CHEROKEE COUNTRY Even though i show 3 codes PO108, PO118, PO171 It Starts good but when u give it gas it has hesitation especially if you floor it. Will run at normal speed 50 55 good for about 8 9 miles. Cut off go in store come out, start it and it miss bad barley will run. cant hardly push the pedal down or it dies or will die at idle Once it dies it wont start. Like NO FUEL OR NO SPARK but then you HAVE SOME ONE pour gas down the throttle body little at a time,cap your thumb over pop bottle slight opening. while i crank it and pump the gas pedal and it finely picks up and will start and run, Does good normal speed home except flooring it to pass. boggs down at first then will finely pick it up. does same thing giving it gas setting still. so even with the 3 codes is it my fuel pump???
