not sure how similar the setup is between your car and the 205 but i'm assuming you can't scan for fault codes. The pump circut should run through a fuse check the fuses in car and under the hood. One may be blown. If that reveals nothing try to borrow another ECU if you can get one from an RC185. If that works it should save you hours of ugly trouble shooting. Other than that you may have to pull the car battery and run through the harness with a multimeter continuity tester to try to work out what's going on.
