Truck won't start

So a few times I've had to pull the truck into gear and back to park in order for the engine to start when I turn the key. Now after driving around and stopped to hook up to my trailer, I turned engine off adjusted the ball then tried starting and no luck. Tried the gear shift thing and still nothing. 12 volts in battery, but cannot roll up windows, horn is faint, lights go dim on dash when I turn key. No sound no nothing just dead. Any ideas?

 

If the battery is confirmed good it sounds like a connection issue of some sort. Have you tried to jump start? If so, what happens?

 

Dead battery, there may be a dead cell in there.....

 

But the battery shows 12.5 volts using my multi meter. I don't believe it's the battery.

 

Nothing. Same same

 

You got to load test it. I'm betting on the battery being bad.

 

But the last few times when I took it out of park and back, turned the key, the truck started no problem.

 

Have you tried starting from Neutral?

 

Yessir! Same as if in park

 

Good thinking

 

Starter... just re-read your original post....

 

you can try jumping the relay, you will need to look up which way to jump.. Wire or paper clip

 

Thanks a bunch pal, I will try that and google it lol.....stay tuned

 

There is a vid on youtube an 08 sequoia, that's how I identified mine.

Dead cell in battery and my buddy has a load tester
They did an AVR test and everything else electrical checks out.
Thanks guys!
