TRUCK WON'T START

2003 Ford Explorer • 133,000 miles

2003 Ford Explorer Sport Trac XLT

My truck won't start. I'm hearing a few different clicking sounds. Sometimes I hear a faint, fast clicking sound before I even attempt to start the truck. Once I do try to start it, sometimes it clicks once, then nothing. Sometimes it will click repeatedly when I turn the key. However, when my headlights are turned on, it doesn't click at all.

I cleaned the battery cables, nothing.
I replaced the battery, nothing.
I had the starter tested, it is fine.
Not sure what to try next.

**I apologize if this question was submitted twice.

Check the 2fuses that are pictured then check starter relay with a like relay then check voltage at battery and voltage at starter to see if they are the same. If not check your cables they may have corroded.

Great thank you.

Let me do the fuses first. How do I know if they are bad? Please see image.

Could it be an ignition switch?

I'm sending the starting circuit diagram along, it could be ignition switch but it cold also be relay or poor battery as all of that has to be checked that I said in previous reply
