Category: Toyota
Expert:  Ted Ritter replied 1 year ago.

Hello, thanks for posting

Does the engine turn over but not fire up?

What year Tundra is it and which engine?

Customer: replied 1 year ago.
The battery died overnight, this morning I jumped it. It's just turning iver and not firing. 2007 5.7L
Expert:  Ted Ritter replied 1 year ago.

Thanks for the reply

Have checked the fuses in the box under the hood?

Expert:  Ted Ritter replied 1 year ago.

Are you using the same key that worked before?

Is there any kind of aftermarket security system or any security light on the dash flashing?

Customer: replied 1 year ago.
same key, there is a red car symbol to right of clock flashing.
Customer: replied 1 year ago.
No aftermarket stuff except brake controller. Fuses seem fine
Expert:  Ted Ritter replied 1 year ago.

What does it look like? Is it the shape of a car or a key? Or just a led light? The security system activated when the battery died and it's keeping it from starting.

Customer: replied 1 year ago.
A key symbol in a red car symbol
Expert:  Ted Ritter replied 1 year ago.

Ok, that's the factory sec system, do you have a remote for it?

Customer: replied 1 year ago.
Customer: replied 1 year ago.
I have remote
Expert:  Ted Ritter replied 1 year ago.

Ok, close all the doors, use the key to lock unlock five times, I''l be back in a few minutes.

Customer: replied 1 year ago.
Use the key manually in the door?
Expert:  Ted Ritter replied 1 year ago.

Yes, I also wanted to ask if you put the key in and turn to ON does the light still flash?

Customer: replied 1 year ago.
No, the light stops when key is on/inserted
Expert:  Ted Ritter replied 1 year ago.

Ok, that's good, it means the computer is recognizing the key. Try this, it's kind of a long shot but it may reset the sec system:

With the key out disconnect the negative battery cable

Put the key in and turn to on

reconnect the cable

try to start

if that doesn't work

disconnect the battery for about 30 minutes and retry

If neither works please relist the question without leaving a rating so someone else can help with this, I have to leave for a few hours anyway, good luck, hope you get this resolved.
