i have replaced the fuel pump on my kia three times in the past six months. Everyone I take it to keeps telling me that is what the computer is reading is wrong with it. It just loses all power while going down the road. The rpm goes all the way down even with the gas pedel to the floor. Has anyone else had this kind of trouble, if so, please let me know what had to be done to fix this. Thanks
Are all the pumps not working when tested ? seems a bit unlucky to get 3 bad pumps ? have your tech's check the TPS ?
Throttle Position Sensor
Throttle Position (TP) sensor resistance increases linearly as throttle is opened. TP sensor sends a voltage signal to ECM (throttle angle signal). ECM uses this signal to calculate fuel injection duration. TP sensor is located on plenum-mounted throttle body.
