To check the fuel pressure on a 2001 Nissan Frontier with a 2.4L engine, you'll need a fuel pressure gauge. First, locate the fuel pressure test port on the fuel rail, typically covered by a cap. Remove the cap, connect the gauge to the port, and turn the ignition key to the "ON" position without starting the engine to check the pressure reading. The normal fuel pressure should be around 36-44 psi; if it's outside this range, further diagnosis may be needed.
