Test NTC-3A - Checking Fuel Pressure
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
High fuel pressure may be present in fuel lines. Open fuel system with caution. See FUEL PRESSURE RELEASE
in this article.
NOTE:
After each repair, perform TEST VER-2
.
- Release fuel pressure. Connect fuel pressure gauge to fuel rail. Turn ignition on. Using DRB, actuate fuel system test. If fuel pressure is 43-53 psi, test is complete. If fuel pressure is not 43-53 psi, go to next step.
- Record fuel pressure reading. If pressure is more than 53 psi, go to TEST NTC-3B . If fuel pressure is less than 53 psi, stop fuel system actuation test. Go to next step.
- Turn ignition off. Inspect fuel lines for kinked or restricted lines. Repair fuel lines as necessary. If no kinked or restricted lines exist, go to next step.
- Release fuel pressure. Remove fuel pressure gauge from fuel rail. Install fuel pressure gauge between fuel tank and fuel filter at rear of vehicle. Turn ignition on. Using DRB, actuate ASD relay. If fuel pressure is at least 5 psi more than previously recorded pressure, replace fuel filter. If fuel pressure is not at least 5 psi more than previously recorded, go to next step.CAUTION: DO NOT allow fuel pressure to exceed 60 psi when squeezing fuel return hose.
- Gently squeeze fuel return hose while observing fuel pressure gauge, ensuring fuel pressure does not exceed 60 psi. If fuel pressure increases, replace fuel pressure regulator. If fuel pressure does not increase, replace fuel pump and sock assembly.
