First! Thanks for the patience in answering my posts to date! This is a
neat little car but with the ECU thing I get a little twitchy about
useing brute force and ignorance. Hence the many questions. On my VW bus it is
hard to kill anything electrical! No brain box. ;-)
Newbe questions:

1) Is it normal to be able to hear the main fuel pump?
2) Is it normal for the fuel pump to vary up and down
with regard to the sound. Sounds like it speeds up and slows down
over an over.
3) If this isnt a normal operational sound, would this indicate a bad
in tank fuel pump? (I'm planning on pulling it out and check the filter anyway)
4) How do you test the in tank fuel pump to see if it runs? which wire is +12vdc
and which is ground for the fuel pump?
5) West coast: Floor pan rust behind both front seats right where the metal
starts to go up.. typical? Where is the water coming from? seems to be a wire tunnel next to the driver's seat... is there a seal that may be shot?
6) Testing idle control system: Does the idle screw have any effect?
the manual says to go to ground at the ecu but had advice to jumper to ground
at the connector in the engine compartment (blue/white wire). with this done
it supposedly removes the solenoid from the equation and then you set the idle with the screw. Then remove the jumper to ground. comments?(cant see it on the schematic I have)
7) The connector by the battery that isnt plugged into anything (the one with
the blue/white wire) is this just a test connector or should it be plugged into
something important?

My daughter bought this car and I get to get it up and running well. As I have worked on it I actually like the damn thing. having suffered from VW addiction
for years this is a scarey feeling! ;-) To many hobbies as it is!
