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

[STRAIGHT from SanFran]

I'm no Buick expert but I would pull the codes and look for some form
of electrical problem. Always remember that grounds are as important
as anything else in a circuit. (I once spent hours and dollars on a
problem only to find a poor ground)
The ignition switch is a good suggestion; they aren't that expensive,
just time consuming to replace. Correcting the problem with the on -
off cycle would make that a first guess.

> 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.)

> 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 ???
