Testing Fuel Pump Relay?

Is there a way to test the fuel pump relay for the 83 Rabit GTI? They're
kinda expensive. The part number is 433 906 059 .
Thanks,
Fred

Do the jumper wire as mentioned in the Bentley section on fuel
injection testing. If the pump runs with jumper wire you know all your
wiring is good. If pump does not run with a crank of the ignition then
the relay is probably bad. I had one fail on my 84.

$15 is kind of expensive?

Thanks Jim. Advance Auto wanted 40 or 50 bucks (depending on whether it was
made in Germany or not).
I did the jump and the pump worked. I also tested terminal 15 on the relay
socket for power when ign. turned. It came on right on cue, so it must be
the relay.
I had bypassed the relay a long time ago and one of the wires to the pump,
but I believe this also disables the thermo time switch and other goodies.
Stay in school.

The web is your friend. I start with http://www.germanautoparts.com/
and then I go to http://parts4vws.com/ and
http://tdiparts.com/catalog/index.php

I start with German Auto Parts because they are on the same side of
the country as me so shipping is less and faster than Parts4VW. Since
I now have a TDI my parts searches go to some other places.

I google for lawnmower parts, bicycle parts, auto parts and other
shopping things. The local supply houses often disappoint in price and
lack of OEM parts. The only thing I seem to not be able to internet
shop is Still parts. They seem to have some internet sales ban. Or
they used to.

rockauto.com also has good prices on vw stuff. my 85 cabriolet main
fuel pump died the other month and fried the relay. advance showed as
being able to order but when i went in they said they couldn't get it.

there are five male connectors on the bottom of the relay
, one small , two twice that size ( med.)
and two twice as large ( big ) as the med..
the two big ones are the ones that pass
power back to the pump and with a ohm meter will read open till there is 12v flowing
through the coil in the relay. (the two med. terminals ).. So if you connect your ohm
meter to the two big terminals then jumper one side of the battery to one med. terminal
and the other side of the battery to the other med. terminal you send current through the
coil and you'll hear the click of the switch and see the ohm meter reading real close
to zero ohms. that fifth terminal connects to a bunch of solid state devices in the relay
and i really have no good way to check that portion.

Thanks. I already order a new one. The old one would kick in but only for a
few seconds. Not sure why. I took it apart and was surprised how much stuff
they packed in there. Anyway, let's hope the new one stays on.
Thanks again everybody!!!

Does your '85 Cabriolet have 2 fuel pumps? A transfer pump in the fuel tank
and a main pump to pressurize the system?
If the main pump went out it may have been due to a bad transfer pump.
