Check Fuel Line Pressure

Start the engine with the fuel pump disconnected to reduce the internal pressure of the fuel lines and hoses, and wait until it stops by itself.
CAUTION: Be sure to reduce the fuel pressure before disconnecting the fuel main pipe and hose, otherwise fuel will spill out.
Disconnect the battery negative (-) terminal and then connect the fuel pump harness connector.
Using the fuel pressure gauge, adaptor and connector, install the fuel-pressure gauge to the fuel delivery pipe.
Connect the battery's negative (-) terminal.
Check that there is no fuel leak from the pressure gauge or connections.
Start the engine and let it idle.
