no start 1989 240, spark ok, tailpipe smells of fuel 200 1989

Your car may still have a cold start injector underneath the intake manifold on that year.
You could always disconnect it.

If it smelling from underneath the hood or from the tailpipe ... that's got to be a lot of gasoline not vaporizing in the right place. I believe it's called "raw fuel."

You will need to pull the plugs and spin the engine to vacate the cylinders. This will help in the next go-round of cranking to start.
Before you put them back in bundle them together tightly with the wires attached. Ground them on the engine someplace. When you roll the engine to fire them, see if they are all sparking nicely in a rhythm. This checks the rotor and the caps integrity in case you need a tune up.

In extreme cases, excess fuel is washing down the cylinders walls and diluting the oil in the pan.
If the oil starts smelling of gas from the dip stick I would change the oil as soon as you find the problem.

If your car does not have the cold start injector, you could have a bad Engine Coolant Tempature sensor or a disconnected one. It talks to the ECU to set mixture and is under the third cylinder intake runner. The ECU might think the engine is in Alaska someplace.

I'm suspicious that you are not saying that the engine is popping or producing short spins of running.
The timing could be way off if the timing belt is in bad shape or has jumped.

How long since its had a good massage of maintenance?

Phil
