2008 taco not starting

Hello taco friends
I have a 2008 Tacoma v6
That randomly starts and doesn’t start
It just cranks and there’s times where you wait 30 minutes and it fires back up
Other times it starts like normal for weeks
I’ve had many parts replaced even the ecu was replaced without luck
It’s like the truck is haunted lol
Any suggestions will be greatly appreciated

 

Can you tell us what parts were replaced?
This will help us, help you.
That way we don’t suggest things that have already even tried.

Is it possible you have an immobilizer problem?
Does the security light on the dash flash when this happens. (Just like it does with the key out of the ignition)

 

Hello there
Yes scanner showed code B2799
Replaced ecu and recoded key and it was fine for a few days until today
It was crancking for 30 minutes until it fired back up took it directly home

 

Btw the security light goes away when you stick the key in the ignition

 

That is an immobilizer code.

Service Manual says it’s either the ECM or the wiring between the Transponder ECU and ECM.
Since you’ve replaced the ECM, you might need to start checking wiring.

See here for a case just as yours. - (It was the wiring)
