Test NS-2A - Inspecting Fuel System
WARNING: This page is about a different car, the 1994 Plymouth Acclaim and 1994 Dodge Spirit. 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
.
- 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, using DRB, read Throttle Position Sensor (TPS) voltage.
- If voltage is less than 1.5 volts, go to next step. If voltage is more than 1.5 volts, disconnect TPS connector. Inspect terminals. Repair as required. Perform TEST VER-1. If terminals are okay, replace TPS. Perform TEST VER-1 .
- If vehicle is not equipped with a factory vehicle theft alarm, go to next step. If vehicle is equipped with a factory vehicle theft alarm, using DRB, read theft alarm status. If DRB displays FUEL ON, go to next step. If DRB does not display FUEL ON, refer to VEHICLE COMMUNICATIONS TESTS in TESTS W/CODES - TRAVELER MODULE article in ENGINE PERFORMANCE section.
- Using DRB, 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 DRB, actuate fuel system. Observe fuel pressure gauge. See FUEL PRESSURE SPECIFICATIONS table.FUEL PRESSURE SPECIFICATIONS
Application psi (kg/cm2 ) With Flexible Fuel 50-60 (3.5-4.2) - If fuel pressure is more than specification, go to TEST NS-4B . If fuel pressure is less than specification, go to TEST NS-4A. If fuel pressure is within specification, go to next step.
- Go to next step.
- If vehicle initially started and stalled repeatedly, go to TEST NS-7A . If vehicle did not initially start and stall repeatedly, go to TEST NS-3A.
