code po171
The fuel pump relay is in the fuel pump itself, Therefore when your relay goes bad or you get a 5-4 trouble code you must replace the fuel pump.
Yes it could. If the fuel pressure is too low, the system can set a fuel system lean trouble code.
Kia does not use a fuel reset. If you are having trouble with the fuel pump check the relay. If it is good you could have a bad pump or a bad ground at the fuel pump, a bad ground is a common problem on these vehicles.
IF that's what happening, low fuel pressure(bad fuel pump)or bad fuel filter.
A fuel pressure test done at the fuel rail will verify the condition of the fuel pump. Before going to that much trouble check the fuse, and fuel pump relay. If either one is defective the fuel pump will not function.
If the relay is bad, then the fuel pump will not work.
bad fuel pump bad fuel pump
Bad fuel pump, blown fuel pump fuse, bad fuel pump relay, or clogged filter.
Could be either. Start with replacing the filter then if it still has trouble do a fuel pump pressure and leak down test.
If it does not start, beat on the bottom of the Fuel Tank with a 2x4, and it starts, then the Fuel Pump, is bad. If it dies, while running, it could be One of several things, from Oil Pressure Switch, Fuel Pump Relay, Injector Screens, Fuel Filter, or in the ECM. Scan for Trouble Codes.
If your fuel pump is not running , it could also be the fuse for the fuel pump relay , the fuel pump relay , a bad electrical connection , or a bad fuel pump
A few possibilities could be the fuel pump relay is bad, the fuel pressure regulator is bad, the fuel pump circuit wiring may be bad and maybe the new pump is bad.
