I put a 2006 Nissan Altima engine for my 2003. My car will start and run but it will shut off within seconds. I got code P0335, I replaced the crank sensor and the car still not starting and I'm getting the same code. Computer also says different or new model. What did or am I doing wrong?

Hello and welcome to 2CarPros. P0335 is a circuit code, those are usually either the plug or the wiring has a break in it between the ECM and sensor. The cam and crank sensors share the ground and power circuits. Power is on the red wire and ground is the black wire. The white wire in both are the signal feeds to the ECM. I would use a test light to confirm the power and ground at the connector. Then trace the white wire to the ECM and check it for continuity. If you have access to a scope you could back probe the signal lead and see if the signal is actually there at the ECM as well.
Not sure on the new model item. What is saying that the scan tool or?
