2014 Ford Escape engine won't turn over with new crank-angle sensor

The probability is that you’ve disconnected something electrical to change the crank-angle sensor and failed to reconnect it afterwards. It sounds simple, but it’s a common problem. Either that or the car has been sitting for long enough for the battery to lose its charge.

So start with the basics. Check that the battery is charged up and that the terminals are connected properly and are clean and tight. There may also be a fusible link in the positive terminal that might have blown during the reconnecting process. Then, make sure the earth cable from the battery is, indeed, earthing on the engine or body of the car (preferably both).

If there’s still no joy, you need to check for power at the starter motor. If there’s no electricity getting to the starter or its solenoid, the engine will not crank. If that’s the problem, you need to start chasing the break in electrical continuity, starting with the fuses and relays that control this circuit.
