Question about 1991 Chevrolet Lumina
It's probably the crank position sensor. That's what it was on mine. From under the car (on a hoist or jack stands of course) look up between the oil pan and the flat transaxle plate. You will see the sensor, unplug the two wire connector then remove the #8 bolt to get the sensor out of the engine block. This is NOT an easy task if you have hands bigger than a four year old but it can be done with patience.

Three things an engine needs to run, fuel, spark and compression.
If you remove a plug wire, insert and screw driver ( don't damage the terminal in the boot) hold it close to the engine and have some one crank the engine over, do you have spark?
If so, check the fuel pump pressure? install a pressure gauge. When you crank the engine over, you should have 30 to 45 lbs. of pressure immediately.
And last, When you crank the engine over, does is sound normal, in other words, a rhythmic sound.
If questionable, remove a spark plug, install compression gauge and record pressure.
Let me know what you find and we can proceed.
