To test the fuel pressure on a 1996 Suburban 1500, first locate the fuel pressure test port on the fuel rail. Use a fuel pressure gauge, attaching it securely to the port. Start the engine and observe the gauge reading; it should typically be between 58-64 psi when the engine is running. If the pressure is outside this range, it may indicate a problem with the fuel pump, filter, or pressure regulator.
