hey folks.
I'm diagnosing some weird behavior on my 97 jetta aaz, and part of that invovles replacing the fuel shut off (specifically, it wont turn off when I start it, but it idles fine, so its not a turbo related issue, I expect).
unfortunately, I can't seem to get the dang thing out. any suggestions? I can get a wrench on there, but there's not enough space to do it, and not enough space to get a socket on there. I really dont want to have to undo injector lines to get in there.
advice?

Try unhooking the power from the stop solenoid when the car is running and then see what happens.
You have to take the lines off to remove the solenoid

When it gets down around -50F my rabbit won't shut off either, just kinda slowly idles down until it's chugging real low. I usually try a couple times and then just let the clutch out.
I've never figured out nor really cared what causes it since I try not to drive it at those temps anyways

Wow...at THOSE temps the poor Rabbit is probably afraid he will die if he allows himself to be shut off!!!

ho hum. I guess I'll have to take the lines off. bugger. I was hoping it to be a minimal effort sort of thing.
I should probably get that bentley, then. no use in winging this one and ***ing it up..
on a sidenote: -50f? sweet baby jebus.

Did you try unplugging the stop solenoid while the car was running to see if it stopped? Usually they fail shut, not open.

its the best guess I've got on my hands.... the car kept consistent idle for a solid ten minutes as I cleaned up (post fuel filter change - my first on a mk3, but Ive done plenty on a mk4 without issue), and then just wouldn't shut off. I tried this twice.
the voltage for the connector is correct too.
any other things I could check other than this? because once I install it, I have to keep this $100 solenoid

$100? What the FRICK?
The lines are dead easy to take off
and have you definitely taken the power off of the stop solenoid. You do realize that turning the key OFF cuts power to it and it CLOSES right?
the wire doesn't go to it to tell it to turn off it is there to keep it open to run the car.
i've never even heard of a solenoid failing open.
my bet is that the problem is in your ignition.
Speaking of which, how do you eventually get it to stop?
ps. you don't need a bentley to take the lines off. you need a wrench.

some fuel solenoids are normally open, and electricity closes the solenoid and shuts it off. its so when the electronics die on the boat, the engine continues to run until 12v is supplied to the fuel solenoid. then you arnet stuck out in the ocean with a dead engine because your wiring job sucked. i think its a better idea anyway. i would rather have 12v to kill my engine, rather than 12v keeping it running. cause your whole 12v system can fail, but the engine will continue to run this way. if you use VW fuel solenoids, no power = no run.

There should be no need to remove any lines? I think I did mine last summer with a set of channel locks.

lines come off with a 17mm IIRC. To get a wrench in there to prevent damaging of the solenoid, the lines should really be removed.

I put it in gear and stalled it. how else?
I don't think its an ignition issue... there's definitely voltage when its in acc, and no voltage otherwise...

When it gets down around -50F
Clucking Bell! That is unfeasably COLD. -45C.
You should see the chaos in the UK with -10c and two inches of snow.
