I put the key in the ignition and it cranks but will not start. I know it could possibly be the crankshaft position sensor but I am not sure where it is. If it is not that what else could it be?

Hi and thanks for using 2CarPros.com.

A bad crankshaft position sensor can cause a no spark condition, so before we just replace it, lets check if that is the issue. Here is a link which describes how to check for spark:

Next, lack of fuel or low fuel pressure can also cause it not to start. Here is a link which describes how to check for fuel.

Also, here is a link which describes a no start condition with possible solutions:

If the check engine light was on in your vehicle, that could be very helpful. When it is on, there are trouble codes stored in the computer which will indicate problems. Here is a short video showing how to scan for codes:

When you check for fuel pressure, your specific vehicle should be right around 55psi. I have attached pictures specific to your vehicle to check pressure. The pictures are directions for diagnosing problems with the fuel system.

I hope this is helpful. Please let me know if you have any questions or just need help.

Take care,
Joe
