1994 Ranger 4.0 V6 cranks but won't start. Tried all the normal things. Grasping for straws here. One weird clue.

Since all else seems to have failed, try banging on the fuse box. That wasn't a permanent fix for me but it worked sometimes. I also had flooded engine symptoms sometimes. The big clue was that I couldn't hear the fuel pump immediately after turning the ignition on. I checked the kill switch under the dash on the far right of the passenger side. Relay was also good. Ultimately, I had to replace the fuse box. What a pain!
