Low Fuel Warning

WARNING: This page is about a different car, the 1990 Acura Legend. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Do not smoke while working on fuel system. Keep open flame away from work area. Drain fuel only into an approved container.
  1. Park car on level ground.
  2. Drain fuel tank into an approved container. Then install the drain bolt with a new washer.
  3. Add less than 2.9 gallons of fuel and turn the ignition switch on. The low fuel warning light should come on within 4 minutes.
  4. Then add one more gallon of fuel. The light should go out within 4 minutes.
    • If the warning light did not come on in step  3, remove the maintenance access cover and disconnect the 3-pin connector from the fuel gauge sending unit. Connect the "C" (GRN/RED) terminal to the "A" (BLK) terminal with a jumper wire. See Fig 1.
    • If the light comes on, the problem is either the sending unit or its ground.
    • If the light does not come on, the problem is an open in the GRN/RED wire to the gauge assembly, no power to the gauge or bad bulb.
