Sure batt cables are tight? Batt voltage at least 12.6 sitting overnight?

 

New battery now. Everything is tight.

Also check chassis to engine grounds.

 

I’ll check this tomorrow afternoon.

Toyota likes to run one from either the fender well or firewall to the intake pleunim.
On the 3.4 V6 that's the primary ground the ecm uses.

 

Thanks, I’ll find it or find someone who can...

I pulled the first heat shield to where I could see the base of the starter and gave it a few taps with a steel bar and a hammer. Starter engaged. It had been drawn down to 9 volts from yesterday afternoon’s searching for a problem. I jetted to town and got a new battery this morning. Has started every time by once all day today. We’ll see how it does overnight. #3 son says he’ll come over Sat morning and help me (do the work) with changing it out. Until then I have the steel bar and ball pin under the seat. I had a T100 once and changed the starter on it twice. I just carried the bar with me after that. But it was easy to get to. My first Tundra was in 2008. I changed the oil once and have had it done since then. This starter thing is way beyond and oil change PITA…. I can’t complain too much though. I bought this Tundra new, replaced all the rotors once, pads twice, three sets of tires for 165K miles… fed her regular gas and kept the oil changed…

Thanks for the replies...
