Hi, I replaced my crankshaft position sensor with a authentic motorcraft new one. But the truck would not start. So I put the old one back on and it starts right up. What could be wrong or what am I doing wrong.

- In theory, theory and practice are the same. In practice, they are different.
What engine do you have? We would like to move your thread to a more appropriate forum. This particular area is for 2019 and newer Rangers and you claim to have a 2004.

If it's not broke, why are you fixing it?

Thx
New crank sensor is bad or installation was, it happens
Intermittent no start wouldn't be crank sensor, for sure, 100%
What codes are there in the computers memory?
If none then not crank sensor or cam sensor
Does the Theft light(padlock) ever flash rapidly when there is a no start?
If engine cranks, starter motor works, when there is a no start then usual issue is fuel, pump is intermittent

Don't believe there is a code for the Crank Sensor, on a 2004. Yes, there is codes for the Cam Sensor. Always replace the Crankshaft sensor Electrical plug, with pigtails, when replacing the crank sensor--Had so many of these pigtail connectors, cause intermittent issue, couldn't begin to count them. Never a code, cause it doesn't exist!
Do you have a tachometer?? One trick I used back in the day, was observe, during engine crank/no start, if the tachometer needle, showed crank speed/200-300rpm movement--usually means PCM/Engine computer was receiving Crank Shaft Sensor signal. Hope this helps.
