1990 Royale 88 won't start

I have a 1990 oldsmobile Rolyale 88, 3.8L with 172,000 miles, and it won't start. It doesn't even turn over for that matter. It has a new battery so i don't think that that's the problem. I'm not sure whether it's the spark plugs or if it's an engine problem. Thanks for all the help ahead of time.

Welcome to AF, very general non-specific query, do you mean the engine won't spin/crank at all or it does spin over but not fire?

It doesn't fire. and when it does fire, it just shuts off again. and it spits out a lot of smoke.

Check for fuel pressure, check for raw fuel in the vacuum hose at the regulator. This is step one in the diagnosis.
