I have a 99 GMC Jimmy that only has trouble starting as the gas tank goes below half tank. Full tank and it starts right up. Ive already done plugs and wires. Roter was coroded and I replace that. Replace fuel pump and that seemed to finally fix it for a few months. Now its doing it again. Check engin codes read lean fuel on bank 1 and 2. Cleared codes and check engin lights have not come back on, still has trouble starting. Could I have another bad fuel pump or is it something else. Any help would be usefull please. Thanks.
