My Denali has been acting up for a few months now and the problem has got worse. First the engine would just cut out briefly but continue to run, I cleaned everything up, MAF, throttle body etc., then it ran good for a month. Then same problem plus the motor would stall and hard to start. I replaced the fuel filter again, plugs, wires, new mass air flow sensor and O2 sensor on the right bank, code was present. that lasted 50 miles, then same problem. Replaced the fuel pump, OEM yes, now while driving the motor just shuts off and hard start! No codes, WTF! Electrical? Any help would be appreciated. thanks.
