Fuel Pressure Check
WARNING: This page is about a different variant/trim than selected.
Release fuel pressure. See FUEL PRESSURE RELEASE . Install Fuel Pressure Gauge (014-00748) between fuel rails. Ensure pressure gauge drain valve is closed and main valve is open. Using jumper wire, connect Data Link Connector (DLC) fuel pump terminal to ground terminal. See Fig 1 . Turn ignition on, but do not start engine. Observe gauge reading. Compare gauge reading. For 1995 fuel pressure specifications, see FUEL PRESSURE SPECIFICATIONS article. For 1996 fuel pressure specifications, see FUEL PRESSURE SPECIFICATIONS article. Proceed as follows:
- If fuel pressure is zero, go to appropriate NO FUEL PRESSURE.
- If fuel pressure is low, go to LOW FUEL PRESSURE.
- If fuel pressure is high, go to HIGH FUEL PRESSURE.
- If fuel pressure is normal, go to FUEL INJECTOR TEST.
