- Turn ignition off. Disconnect fuel pump connector at fuel tank. Crank engine for 10 seconds. Turn ignition off. Disconnect negative battery cable.WARNING: High fuel pressure may be present in fuel lines. Open fuel system with caution. See FUEL PRESSURE RELEASE at beginning of article.
- Connect fuel pressure gauge and adapter to fuel rail. Reconnect negative battery cable. Connect jumper wire between battery positive terminal and single-wire fuel pump check connector Black/White wire located near battery in engine compartment. Ensure no fuel leaks are present.
- Disconnect jumper wire to fuel pump check connector. Start engine and idle. Disconnect and plug fuel pressure regulator vacuum hose. If vehicle is a non-turbo, fuel pressure should be 47-54 psi (3.3-3.8 kg/cm2 ). If vehicle is a turbo with M/T, fuel pressure should be 36-44 psi (2.5-3.1 kg/cm2 ). If vehicle is a turbo with A/T, fuel pressure should be 41-50 psi (2.9-3.5 kg/cm2 ). If fuel pressure is not within specification, repair as necessary, and perform TEST VER-2. If fuel pressure is within specification, go to next step.
- Reconnect vacuum hose to fuel pressure regulator. If vehicle is a non-turbo, fuel pressure should be 37-43 psi (2.6-3.0 kg/cm2 ). If vehicle is a turbo with M/T, fuel pressure should be 26-34 psi (1.8-2.4 kg/cm2 ). If vehicle is a turbo with A/T, fuel pressure should be 32-38 psi (2.2-2.7 kg/cm2 ). If fuel pressure is not within specification, repair as necessary, and perform TEST VER-2. If fuel pressure is within specification, perform TEST DR-19A.
