Re: Explorer 4.0 SOHC won't run
a bad O2 sensor would still allow you to run the engine. I'd get the crank position sensor tested and the O2 sensor replaced.
One thing you may be able to try, not that it will work but it's worth a try - disconnect the negative battery cable for as long as you can (overnight for example) and then reconnect in the morning to see if it resets the PCM. If it works you'll get at least one start out of it to get it into a reputable shop for a proper scan.
