Recheck your work and make sure the sensor is tight and clean. It sounds like the timing is getting advanced or the sensor itself is bad again.

The crank sensor can cause the engine not to run at all. However, it can cause other problems too. I can't guarantee that is the problem, but at this point, it seems to me that is has something to do with it.

A crank sensor is what identifies the ignition timing. I have seen them cause timing problems, engines that run and then shut down.

If the code you are getting is a crank sensor, my guess is that is where the problem is coming from.

I doubt they replaced them. If you pull the #4 spark plug out, what does it look like?
