What to do if you have a fuel line problem?
Turn the ignition switch OFF. Release the residual pressure in fuel line (Refer to “Release Residual Pressure in Fuel Line”). 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.
When to release residual pressure in fuel line?
1. Release the residual pressure in fuel line (Refer to “Release Residual Pressure in Fuel Line” in this group). When removing the fuel pump relay, a Diagnostic Trouble Code (DTC) may occur.
How to check fuel pressure in Hyundai Elantra?
Inspect fuel leakage on connections among the fuel feed tube, the delivery pipe, and the SST components with IG ON. 4. Measure Fuel Pressure. 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).
How can I relieve fuel pressure on my car?
If the fuel pump is accessed from underneath, be sure the vehicle is secured on the jack stands before crawling underneath and locating the fuel pump assembly. Unplug the fuel pump electrical connector on the sending unit/pump assembly. Start the engine and let it idle until it stalls. Then turn off the ignition switch.
