How to check fuel pressure in Kia Optima?
3. Inspect fuel leakage on connections among the fuel feed tube, the high pressure fuel pump, and the SST components with IG ON. 4. Measure Fuel Pressure.
What should I do if my Kia fuel pump is not working?
While your assistant turns the ignition on and off, push in on the valve. If your Kia’s fuel pump is operating properly, gas should flow through the valve. If you do see gas flowing through the valve, close it quickly using a screwdriver. If gas does flow through the valve, there is pressure in the gas lines and the fuel pump is intact.
How to check fuel pressure in Kia Sorento?
Start the engine and measure the fuel pressure at idle. If the fuel pressure differs from the standard value, repair or replace the related part (Refer to the table below). Stop the engine, and then check for the change in the fuel pressure gauge reading.
Where is the fuse on a Kia fuel pump?
If no gas flows through the valve, however, move on to the next step. Examine the gas pump’s fuse. You can find it on the driver’s side fender well, inside the fuse relay box.

Can a Kia Sorento run without a fuel pump?
Without gas your Sorento will not run at all. With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all. In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s).
What to do when fuel pressure test fails?
When removing the fuel pump relay, a Diagnostic Trouble Code (DTC) may occur. Delete the code with the GDS after completion of “Release Residual Pressure in Fuel Line” work. 2. Install the Special Service Tool (SST).
How do you change the fuel line on a Kia Optima?
Pull the fuel pump relay out and lay it sideways in the box. Start the engine. It is not likely to start and even if it does it will only run for a second since the fuel pump relay has been removed, which disabled the fuel pump. This procedure will drop the fuel pressure in the fuel line.
