It sounds dumb, but sort of, yeah, it can.
This mostly happens on Chrysler/Jeep vehicles. An internal short circuit from Sensor V+ to Sensor Gnd causes enough current draw that while power flows through the computer, voltage is too low for the computer to operate as designed.
If you suspect you have this problem:
Verify that battery is charged.
Key on: Verify that Check engine does not light up.
Key off: Disconnect crank sensor.
Key on: Verify that Check engine does light up. Power to computer is restored.
Replace sensor.

I wouldn't mess with it if it's a crank sensor. While they are easy to put on if it's anything like newer Chevy's the relearn can ONLY be done at a dealer. I would look into that first because if it is the same, there is no way you are going to get it to run.
Where is the crankshaft sensor located on a 1996 Buick Riviera?
The camshaft sensor is behind the water pump pulley and the crank sensor is mounted just above the crank pulley(dynamic balancer). If the crank sensor is bad . The car will simply DIE. If the cam sensor is bad it will simply not have sequential injector firing and driveability and MPG will be affected.BOBAnswerwhen the water pump pulley is removed you can see a sensor with 3 wires going to it at the top side of the crank shaft pulley. you might be able to see it with a flashlight and a mirror without removing anything. hope that's the right sensor.
