RE: Please assist me! (Jetta Woes)

[Greg Baxter <gbaxter@valleybrook.com>]

Hi Shawn -

I have checked the fuel pump relay, and it's fine. In neutral, it stumbles 
around 500 RPM, then might kick back to life, and might not. Your switch 
analogy is perfect - that's exactly what it's like. I'll try to get home 
early today, and try a few things... It's really a pain in the ass, 
especially since (in theory, anyway) the Jetta is supposed to be our 
reliable car, and the Scirocco is the one that I play with, and almost half 
expect bad things to happen to... (That and the fact that we're still 
paying for the Jetta!)

Another thing - on Jan's page, there is a file which suggests that the 
Knock sensor is screwy, and the contacts aren't clean. Does this make 
sense? (Grrr I hate electrical gremlins) Also - after 3000 RPM, the 
Alternator light flickers. (Like the other problem, only sometimes) I have 
checked the belt, it's good and tight (is there a possibility that it could 
be *too* tight?)

Thanks for the offer to post to the NG, it looks like my posting (from h  
ome) made it... I made the mistake of posting this problem to the list last 
night with the subject 'help,' and my original messages are now clogging up 
Kevin's inbox.

Thanks, as usual.

I dont know ANYTHING about digifuk but i'll give it a shot for you.
(whatever it may be worth to ya.)

My theory's:

The fuel is stopping, IE, the fuel pump is shutting off and on again.
Fuel pump relay, bad connector to the fuel pump? On a CIS car, id suspect
that the freq valve is intermittant causing a slght dip in fuel delivery.
but it sounds like the motor is shutting off all together? If you put it
in nuetral, does it stall or does it continue to idle? it could also be a
transfer pump, lets not forget that little guy. This is how it sounds to
me.

So your saying it runs fine, and then as if somebody were flicking a
switch, poor running and eventually the "switch" gets turned back on
again, right? Is this a correct description?

I think that if the fuel filter were clogged, thats would be it. Clogged
and you would have problems all the time, especially on higher RPM's
where more fuel is in demand. The clogging effect would cut out on you
all the time and get worse until you replace the filter. But since you
say its been cutting out on you then running fune again, id rule out the
fuel filter as the fault.
Again, id suspect something electrical. Like I said in the beginning of
my reply, I know nothing about digifant so perhaps there isnt even a fuel
pump relay like we have in our Scirocco's. (Im sure there is, but have no
proof..)


Whoa, thats a bad word. He said SHOP. Dont go there unless you absolutely
have to and, got some deep pockets. :)

Clogged cat would run crappy ALL the time. Faulty ox xensor would run
rich. I'd discount these as your problems as well.

If you want, I could post this to the VW newsgroup and whatever replies I
see there for you I can FWD them to you? Lemme know. I dont want to post
your message there without your permission.

As always, HTH!
