How long since a tune-up? Any applicable trouble codes? Your obd1, should be able to check some codes, yourself, if your check engine lite still works? If your tbi, you can usually see if fuel injector is leaking? with key off, no fuel injector pulse. Tbi fuel pressure 9--13 psi. Have you checked the coolant temp sensor?

pretty recent tune up, it pours fuel in as soon as you turn on the key and blows black smoke and smells of gas

Maybe the fuel injector driver has a problem? The computer grounds the fuel injector.
