Test NTC-3B - Checking Fuel Pressure

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 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 procedure in this article.

NOTE: After each repair, perform TEST VER-2 .

Using DRB, stop fuel system actuation test. Release fuel pressure. Ensure fuel tank is at least 1/4 full before performing following test. Install fuel pressure gauge and adapter between fuel tank and fuel filter at rear of vehicle. Go to next step.
Remove fuel return line from fuel pump at fuel tank. Connect Fuel Pressure Test Adapter (6541) to fuel return line. Place other end of adapter hose into an approved 2-gallon gasoline can. Turn ignition on. Go to next step.
Using DRB, actuate fuel system test. Observe fuel pressure gauge. If fuel pressure is 50-60 psi, repair fuel return line for a restriction at fuel tank. If fuel pressure is not 50-60 psi, go to next step.
Stop fuel system actuation test. Release fuel pressure. Reconnect fuel return line to fuel tank. Disconnect fuel return line from fuel rail. Attach Fuel Pressure Test Adapter (6541) to fuel return line nipple at fuel rail. Place other end of adapter hose into an approved 2-gallon gasoline can. Turn ignition on. Go to next step.
Using DRB, actuate fuel system test. Observe fuel pressure gauge. If fuel pressure is 50-60 psi, repair restricted fuel return line to fuel tank. If fuel pressure is not 50-60 psi, go to next step.
Inspect fuel pressure damper line for restrictions. If restrictions exist, replace fuel pressure damper line. If no restrictions exist, replace fuel pressure regulator.
