Does the smoke smell chokey? Thinkin' the mix is wrong due to bad data from the block sensor, the intake air temp sensor and the coolant temp sensor...these things play into the resulting air/fuel combination that you'll be trying to ignite....a couple of seconds before spark plugs foul up? Could this be?

Will it keep running if you put your foot on the accelerator pedal? If so, it's probably a bad IAC (Idle Air Control) valve. HTH. -Jim

I'd replace the purge valve first. Check your vacuum hoses for damage and leaking as well. Could be either the purge valve is stuck open, sucking raw gasoline into the engine and flooding it. Or you have a vacuum leak that's upsetting the air/ fuel mixture. HTH. -Jim

the purge valve failures I've seen in the past have made it so that the tank is difficult to fill...one guy actually used a funnel because the pump kept shuttin' off~

the fuel pump relay---there is one for ten bucks~ https://www.google.com/#q=1997+grand+prix+fuel+pump+relay&tbm=shop

the zinger was "won't shut off"....an unhappy relay will do this~

True, Judge, if the purge valve is stuck shut. If stuck open it'll pull gas into the engine. BUT you made me think of something just now. Perhaps a vacuum is being created in the fuel system because of the purge valve. Try running it a few minutes with the gas cap off. If it starts and runs like that, there we go. Bad purge valve. Thanks Judge! -Jim

https://www.google.com/#q=1997+grand+prix+purge+valve&tbm=shop ____hey, and not too expensive too, if this will help the situation...but the motor staying running can only be a stuck or sticking relay...there ain't no other thing what might cause this situation~

....always suspecting the throttle position sensor...you might put an ohm-meter on this to see if any point it reads zero ohms or a mostly infinite ohms...and should be replaced~
