1991 Toyota 4Runner SR5 2.4L 216000, when I am driving my engine will sputter stall if I don't do my best to try and keep it running by pumping the gas. I have replaced the plugs, wires, distributor cap, fuel and air filters to try and correct the problem with no success. Could there be a problem with the fuel pump, or perhaps a timing issue?

Sounds fuel related. Do pressur3e check on the pump. Also could be the MAF sensor, have seen those have problems at that mileage as well
