It is VERY unusual for a pump to just suddenly stop working, after it has been working fine on a regular basis. I've never heard of a single such instance, although Russ may have. It seem much more likely that you're mistaking the results of your test. Which connector did you connect to with the buzzer? Was the pump connected at that time? If not, it is most likely that the current drain of the buzzer was much smaller than that of the pump, so there was enough power getting thru to confuse you. To do a good test, get a clip lead and jumper around the pump relay, giving the pump a direct source of 12V. If it sparks when you do this you know that you've got continuity thru the pump, a good sign. If it simply runs when the relay is bypassed, the relay is bad; you can open it up and burnish the contacts (NO abrasives or files) or replace the relay. If you get no sparks, first check all the wiring to make sure that it is intact and making good contact with the pump, then put the jumper there and take a small hammer under the car and gently tap on the fuel pump, all around it. DON'T hit it hard, just tap, tap, tap.... Eventually you should break the brushes free and it will start to spin. If this is your problem you should make sure that your overflow hose has not broken and allowed water into the gas tank. It is most likely that your problem is a wiring harness/connector problem or a relay problem. > Is this a replace type part or a fix type part? The odds of taking it apart and fixing it are poor, but they are EXPENSIVE and worth some considerable effort. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
