Check Fuel Pressure

Turn ignition off. Connect fuel pressure gauge to Schrader valve located on fuel rail. Observe fuel pressure gauge. Turn ignition on and note fuel pressure reading. Start engine and allow to idle. Note fuel pressure reading. Increase engine speed to 2500 RPM for one minute. Note fuel pressure reading. If fuel pressure readings are 80-120 psi (552-827 kPa), testing is complete. If fuel pressure readings are not 80-120 psi (552-827 kPa), go to TEST HB under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V article.
