Won't start when cold

I have a 2nd generation Tundra with 110,000 miles that it won't start at least the outside temperature is 75 degree or higher. After that it will run perfectly fine with no check engine light on.

 

Sounds like a bad battery. Cold, although lower 70s is not cold, slows down battery chemical reaction and loses power.

 

It a new battery. Del-co. Just put on. By the way, I live in Florida. It doesn't get that cold over here.

 

It crank very strong and try to start but it wont until weather had warm on

 

Ensure the wire terminals are tight & clean: battery positive & negative, and the grounding wire on the body.

 

Material expansion and contraction might be to blame.

 

Clean Mass air sensor with the item specific cleaner.

 

After it start today I will take it to the shop and check it. any website that may show all the ground point? This is my first Tundra and I am not to familiar with it.

 

Flex fuel? What year, what engine?

 

2010 tundra with a 2014 engine put on in January. Ran find until 2 weeks ago. When the weather is over 75 degree it run like new.

 

I just clean and tide all ground with no resolve.

 

First, Welcome from LA (Lower Alabama)! From the earlier posts it sounds like the battery turns it over just fine, but the engine just won't start to run on its own, but only at relatively cooler temperatures, right? I'll throw an idea at you, but you will get better responses from the Ask The Toyota Mechanic thread, found here: https://www.tundras.com/threads/ask-the-toyota-mechanic.2404/

My thoughts are the fuel filter. Something in there may be gumming up when the temps drop.

 

Welcome from Pa.

 

When back to the truck around 1pm and it just started right up. My obd2 scanner show codes p0118, p0125, p2714 but only in the morning. After it started they go away. In the morning when I crank the engine the code come back. try to erase then but they come back on even without cranking the engine. I change the coolant with 100 % coolant, installed a new coolant temperature sensor with no change. The cts shows 11.6v in the brown wire and 4.1 on the green black stripe wire. I am planing to change the thermostat today and do a pressure text. By the way, I check all the ground I was able to find but no luck

 

Engine is a 4.6

 

PS Two more code showed up today using a snap on scanner. code P0352 and code P1604. When I crank the vehicle in the morning it show the check engine light and the a/t fluid... in red letter.
