[SEL] Off Topic - Car Troubles - Buick - HELP !

A similar problem happened to my 2001 Seville.  The engine  would stall 
when sharply turning the steering wheel especially in a parking  lot.  Turning 
off the ignition and then restart the engine got it going  again.  The 
problem was the cam position sensor.  The following  describes possible Camshaft 
Position Sensor symptoms:
 
"A failed camshaft position sensor will show up in a number of  ways. The 
worst-case scenario is that there is no spark in the combustion  chamber. 
Other symptoms related to the position sensor can include excessively  long 
cranking time when starting cold, rough running on an intermittent basis,  poor 
idle, stumbling or hesitation, a drop in mileage and stalling upon  
acceleration. These position sensor trouble symptoms may also be caused by a  
failure in the wiring of the sensor."
 



Another possibility is a faulty fuel  filter.
By the way, my wife's 2003 Buick will turn off and start the  engine in the 
neutral position.

Hi  List,
I hate to keep coming to the SEL for help with my vehicles but I  have
another problem I can't solve.
The '95 Buick Park Avenue Ultra with  67,198 miles is giving us trouble.
>From a "cold" start, it starts,  tries to run and dies.  Then you have to
turn the key completey OFF,  then restart it.  Then it MIGHT run okay.  
While
I'm driving, It  will run okay, but then stumble a little, like the ignition
is trying to  disconnect, and lights flash on the dash.  If it dies, you 
have
to  drift to a stop, turn the key OFF and then restart it.  You cannot  turn
the key OFF until it is in PARK.  (Which is very embarrasing in  traffic.)
I had two mechanics say it was the fuel pump.  A new fuel  pump and $400
later, the problem persists.
This condition has seemed to  come on gradually.  After running and stopping
at the grocery store,  or what ever, and restarting it, it would run very
rough.  But once  put in gear and moved, it would run okay.  This has
progressivly  gotten worse.
Another thing - - - I'm not sure if this has anythng to do  with it but - - 
-
It seems like it dies after a 90º right turn.  This  has happened to me 3
times in one evening.  I can't imagine any  "dangling" wires or connectors.
The car is like a new car -   immaculate and no rust.  Temperature, Rain or
Sun doesn't seem to  affect the problem.
When it happenes, there is a lot of instrument light  flashing and - for 
some
reason - the Ext. Temp. screen keeps blinking for  about a minute after it
restarts.
It does NOT have an on-board  diagnostic. I don't have a reader and the
mechanic that replaced the fuel  pump just says everything reads fine and he
can't get it to continue what  it's doing.  He would have to be reading it
when it dies.
I'm  tending to think it's a sensor or module of some sort breaking
electrical  connection or smelling something or ???
HELP  !!!
