Question about 1990 Buick Century
The check engine light should be on--rent a scanner, read out the codes, and pursue to repairs. The one sensor you didn't mention is the camshaft sensor. It is a hall effect device and depends on a magnet passing to generate triggers. It is combined with the crankshaft sensor and they work in tandem with the CPU to generate firing. Maybe the magnet came off of the camshaft? If you have access to an oscilloscope, you could look for pulses from both sensors where they go into the ignition module--terminal 'G' for the crank, and terminal 'K' for the cam signal.
