2004 Ford Explorer XLT has random non start. Battery is good

Customer Question

2004 Ford Explorer XLT has random non start. Battery is good and door locks, radio work but the engine won't turn over. Randomly the next time I try to start it it will start fine for mayben even a couple of days.....don't know where to look.
JA: Figuring out why a car won't start can be a challenge - it could be a simple repair, or something a bit more complicated. Fortunately, the mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: yes
JA: Great! What have you tried so far?
Customer: just making sure it is not the battery or charging system. At first I thought it might be a dead battery because the first time it happened my wife had it jump started and it started fine.
JA: Is there anything else important you think the Ford Mechanic should know about your Ford?
Customer: no
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and then connect you two.

Thank you for that information. Have you checked the starter? Have you checked for power down to the starter motor? If not, this would be the next step. It is possible that you just have a bad starter motor.

It will start fine for a couple of days and then randomly not even engage the starter
Expert:  AMEDEE replied 11 months ago.
YUP! A bad starter motor can definitely cause this condition.
Customer: replied 11 months ago.
What is the best way to test that?
Expert:  AMEDEE replied 11 months ago.
With a voltmeter. Just check for battery voltage on both terminals of the starter with the key in the CRANK position when this happens. If both terminals have power with the key in the CRANK position and the starter is not activating, the starter motor is bad and will need to be replaced.

Here is a wiring diagram of the starting circuit.
