Test NS-2A - Inspecting Fuel System

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. 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.

Ensure throttle cables are not holding throttle open. If throttle is held open, repair as required. Perform TEST VER-1. If throttle is not held open, use scan tool to read Throttle Position (TP) sensor voltage.
If voltage is less than 1.5 volts, go to next step. If voltage is more than 1.5 volts, disconnect TP sensor connector. Inspect terminals. Repair as required. Perform TEST VER-1. If terminals are okay, replace TP sensor. Perform TEST VER-1.
If vehicle is not equipped with a factory vehicle theft alarm, go to next step. If vehicle is equipped with factory vehicle theft alarm, use scan tool to read theft alarm status. If scan tool displays FUEL ON, go to next step. If scan tool does not display FUEL ON, see TESTS W/CODES - BODY CONTROL COMPUTER article in the ENGINE PERFORMANCE section.
Using scan tool, actuate fuel system. Listen for fuel pump operation at fuel tank. If fuel pump operation cannot be heard, go to TEST NS-5A. If fuel pump operation can be heard, turn ignition off.
Ensure fuel tank is at least 1/4 full. Release fuel pressure. Install a fuel pressure gauge in fuel supply line. Turn ignition on. Using scan tool, actuate fuel system. Read fuel pressure gauge reading.
If fuel pressure is more than 53 psi (3.7 kg/cm² ), go to TEST NS-4B. If fuel pressure is not more than 53 psi (3.7 kg/cm² ), go to next step.
If pressure is less than 43 psi (3.0 kg/cm² ), go to TEST NS-4A. If pressure is more than 43 psi (3.0 kg/cm² ), go to next step.
If vehicle starts and stalls repeatedly, go to TEST NS-7A. If vehicle does not start and stall repeatedly, go to TEST NS-3A.
