The crankshaft position sensor (CKP sensor) on a 1995 Chevrolet Blazer with the 4.3L V6 engine is located on the passenger side of the engine block, near the bellhousing (where the transmission connects to the engine). It's usually mounted on the engine block itself, fairly close to the crankshaft's pulley. However, the exact location can vary slightly depending on the specific engine and any modifications.
To be absolutely certain, you should consult a repair manual specific to your 1995 Chevrolet Blazer 4.3L V6. A Haynes or Chilton manual will have diagrams and detailed instructions. You can also search online for images of the 4.3L engine in that year Blazer to get a visual reference. Be cautious when working near the engine; be sure to disconnect the negative battery terminal before starting any work.
