Re: Ur-q with mind of it's own.



   On the other side of things when you go to shut the engine off.
   Turn the key off, remove it from ignition yet the engine keeps running.

   Sounds like someone hard wired the fuel pump relay or incorrectly 
   installed a second FP relay. As you know, the fuel pump should 
   definately stop when the key is removed from the ign. I have heard 
   of swapping an early 4k FP relay which doesn't have the pin installed
   for ECU control of the FP, that way the engine never cuts out. Also
   the very early Detection Techniques(aka Superchips) ECU mods
   were implemented(hacked) such that the FP ran all the time the ign
   key was on. A definate safety no no.

   If the engine keeps running w/o the key, that would mean that the ECU
   is still getting  power and is not being switched off. I have installed an
   switched relay to give my ECU *good* switched 12V power, maybe 
   someone was trying to do the same and screwed it up. Time
   to get out the DVM and dig into that great ur-q wiring, and be sure
   to take notes. Good luck.

As I recall, the "lights" and the "ignition" were separate switches
from the key/switch assembly, so it's quite possible that the lights
were correctly switched off, but the main ignition line left active
by a faulty switch.

I saw the "same" behavior from my fusebox wrt the rear window defrost,
as the rad fan overheated and softened (not quite melted) the fusebox,
allowing the rear window lead to connect to some unswitched +12 in the
fuse box . . . unfortunately, stopping the engine the hard way wouldn't
help this one -- took a coupla "dead battery and NO I DIDN'T LEAVE THE
**** LIGHTS ON" cycles to track this one down.
