Need your help pls!! I have 07 CX9 that will start normal on cold but will have difficulty starting when engine is warm, situation is when I turned off the engine after a long drive and started back up after a few minutes of rest the car will start but will suddenly stall like it ran out of gas and as I tried to started up the car will only crank like there is no fuel flowing in. I replaced the plugs, cleaned the mass air flow, cleaned throttle body and flap and checked intake for a possible leak. The car doesnt seem to be misfiring or hesitating when running and also the car starts up if I sprayed starting fluid inside the intake but there is a DTC P0174 and P0171 present. Anyone fixed same issue. Thanks in advanced!
