how to remove crankshaft position sensor from 91 Buick Regal
they did not start the crankshaft sensor till 1992
Bad coils or perhaps a bad crankshaft position sensor.
On the exhaust manifold where the runners meet.
in the ecu
The crank sensor should be on the drivers side of the transmission bell housing. It's more towards the top of the bell housing. The easiest way to get to it is reaching down from the top of the engine just below the valve cover. Atleast that is where it is on my 91 4.0L
Usually on most Vehicles the Crankshaft Sensor is located Behind the Lower Pulley which is known as the Harmonic Balancer.
The Crank sensor in my 91 LeSarre Limited is behind the Harmonic balancer pulley....there are fins on the back of the pulley that line up with the sensor.
Yes there is... It's behind the head and connects to the top of the bell housing.... 10mm socket will be needed.... DON"T DROP THAT BOLT INTO THE HOUSING ONCE THE SENSOR IS PULED OUT..... Make sure the cable has a white stripe on it...
Disconnect plug under driver's seat.
It's in the distributor also called a hall sensor.
its on the left side of the exhaust manifold it should have a wire leading to it
