Hey Eric sorry about the reply on an old forum but its the only thing I could find on the fuses and you probably know. I have a 3.9v6 2003 slt quad cab and there is a check engine light on. I plugged up my scanner and it told me 02 sensor so I checked all fuses and the one under the hood isn’t getting any power to the fuse even with the truck in assecory mode. I asked my dad who is a mechanic for over 60 years and he said that it doesn’t send enough to actually light up the test light. I was wondering if this correct because I thought it would need power to the fuse no matter what even no matter how minute the power actually is.
