Fuel Pump Flow

  1. Remove engine cover. On 9-3, remove fuse No. 32 from driver's fuse box or on 9-5, remove fuse No. 19 from driver's fuse box while engine is running. On 9-3, use SST 83 95 261 fuel line separation tool to disconnect fuel return line to tank. On 9-5, disconnect fuel return line at fuel pressure regulator. Connect a section of test hose to return line. Place other end of test hose in 2-quart (approximate) graduated container.
  2. Activate fuel pump by connecting a jumper wire between fuses No. 4 and 32 on 9-3 Series and fuse No. 8 and 19 on 9-5 Series. Run fuel pump for 30 seconds. Measure volume of fuel flow and fuel pressure drop. Minimum acceptable volume is 1.48 pts. (0.7L). If fuel volume does not meet specification, go to FUEL PRESSURE  .
