Where is the crankshaft position sensor location on 1991 pontiac firebird 3.1L and show picture or video of the location

You posted twice (you have to refresh the page to see your post), so I amalgamated both into one.

There is a video here. You can also click on the images tab for pictures.

The 1991 was a mid-sized sedan created by Chevrolet in Ontario, Canada. The Lumina is equipped with a crankshaft sensor that detects the position of the vehicle's crankshaft, sending data to the sedan's on-board computer. Having the crankshaft sensor allows the Lumina to make necessary adjustments for the engine to work optimally.

Zach, guess what? It doesn't have one. I went around and around with this very same issue with a local car parts supplier. Yes one shows up on the list of parts for this year and engine... it is all done through the pick-up coil and ignition module in the distributor. Tell me more about your problem. I have tons of experience on this make, year and model.

Hope this helps......

Check the crank position sensor. I'm currently having the same trouble with my 88 Firebird. Hope this helps.

The crankshaft sonsor is located between the timing cover and the harmoinc balancer on the passenger side of the engine.

The crank sensor is on the front of your engine behind the harmonic balancer. You will need a balancer puller for a 3.8 and a crank sensor alignment tool to do this lob.

On your 1992 Chevrolet Lumina-Sedan/Coupe 3.1L MFI OHV , the Crankshaft Position Sensor is located: Under hood, passenger side, lower engine area, passenger side of engine block, mounted front of crankshaft pulley
