You said "test the voltage running". Can't do that if it will not start. Don't get butt hurt. Wow, sensitive.

Perhaps I wasn't clear. I gave a sequence of steps. So I'm not sure whats so funny.
You said that before he replaced the starter, he should check the alternator by measuring the voltage while the truck was running, but he couldn't start the truck to begin with. How can he check the voltage with the truck running if he can't get the truck to start? That's what I was trying to point out.

Yes, I see your point. I made the assumption he could get it going with a jump or charge after verifying the battery was good from AZ. If he could not, then we have a clue. If he could get it going, no 14v another clue. I guess my explaining stinks on this one...

It's ok, we'll let it slide. Personally, I think it is funny as hell! By the way, just remember that a lot of us are like Sheldon on the Big Bang Theory, we are looking for a way to pounce on the most tiny little error that someone else makes and then drag it thru the dirt for all to see. Wait to you get my age and you will too.

Going to add this, may be helpful to OP. Talk about Irony. This morning my truck barely started. Real slow turnover. Unlike my other vehicles this one has a AAA battery so rather than fiddle with it I just called them. He came out, tested. I watched, thinking about this thread. The 3.5 year old battery battery tested close to 12v, but the CCA was only 170. Alternator 14v. So.. While a battery can appear ok tested at the posts, its still important to get it tested for the cold cranking amps. Battery replaced under warranty, problem resolved.

On a side note, was pleased to know that my truck turns over so easy in the cold needing only 170 CCA. Thanks Mobil 1 :D

Glad to hear you got it worked out.
This sounds like mine last winter on real cold days. After I called AAA for a jump and the guy tested the battery, he got in and tried to start it about 30 times and it finally started. He informed me he sees this often and is an indicator that the starter is on it's way out. It did that multiple times when it was cold.
I bought a new starter but the problem hasn't shown itself for some time. If necessary I have the tools to change it in a store parking lot if needed.
Probably should change it before the weather turns cold again except right now I am in the middle of changing the EGR purge solenoid and the brake lines that decided to give out over the weekend.
