3.4L, shut it off, then tried to start the next day and it would crank but no fire. I have no spark all fuses are good. There are no codes. I was going to change crank sensor, but my manual doesn't show where it is at, it says how to check it. Am I on the right track??

Hi:
You may be on the right track, but have you checked for power to the coil? Is there a security light flashing when you turn the key? Is the fuel pump working?
