Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Pressure Check (Lack Of Power)
Run engine at idle and check fuel pressure. See FUEL PRESSURE REGULATOR. Disconnect vacuum hose from fuel pressure regulator, simulating wide open throttle. If fuel pressure does not increase 5.8-10.1 psi (.40-.71 kg/cm2 ), replace vacuum hose and repeat test. If fuel pressure still does not increase, replace fuel pressure regulator.
