Transfer Pump Fuel Volume Check (Cabriolet & Fox)

  1. Turn ignition off. To check transfer pump (in tank), remove rear seat (if necessary). Remove fuel sending unit access cover. Disconnect ignition coil secondary wire and jumper to ground.
  2. Activate fuel pump by removing fuel pump relay and attaching jumper wire between terminals No. 30 and No. 87. Terminal identification is molded on fuse/relay panel. If pump does not operate, remove transfer pump wiring harness connector. See Figure . Using test light, check for voltage between Brown (-) and Green (+) wire at connector. If voltage is present, replace transfer pump. If not, repair open or short circuit in wiring.
  3. If transfer pump operates correctly, remove fuel pump relay jumper wire. Disconnect and plug transfer pump output hose. Attach a hose to pump outlet connector and place other end of hose in a graduated container. Activate fuel pump for 10 seconds.
  4. Minimum fuel flow for Cabriolet should be 9 ounces (.31L). Minimum fuel flow for Fox should be 13 ounces (.41L). If fuel flow is low, check fuel tank filter for restriction. If okay, replace transfer pump.
