OK maybe I'm a dummy for not checking these things often. I looked at my fuse panel to make sure the fuses were OK after check engine light displayed. I noticed Fuse slot #2 position was empty. I looked at the owners manual and a Haynes manual and they didn't agree in diagrams.

Is #2 slot an empty slot on a 1997 Ford ranger 2.3L?

 

According to the Ford wiring manual, fuse position #2 is not used on a 97. If you have a check engine light, it is not likely that it has anything to do with the dash fuse panel.

To find out why you have the CEL, go to a dealer or parts store and have the diagnostic trouble codes read. That will lead you to the problem.

 

Go to a parts store first that will do it for free. The dealers don't and they usually charge a lot.

 

I know it sounds stupid, but make sure your gas cap is on tight.

 

I checked that first and yeah it was related. recently I replaced my fuel filler pipe. It was dry rotted. Everytime I filled up with gas I would waste about a gallon which spilled on the cement. I realized I shouldn't top off as usual.
