My name is Dennis, I have a 2001 Dodge Dakota Sport extended cab with a 4.7 an automatic transmission. I am trying to do the crankshaft sensor on this. While trying to do the sensor it snapped off in the block is there anyone that can tell me how to fix this problem. All input is graciously accepted

 

Use a small drill bit, drill a hole into it, thread a screw into the hole, and use the screw to pull it. Don't press too hard with the drill, if you drop the sensor into the engine, life gets a LOT more complicated.
