2014 Tundra Died While Driving and Now Won't Start

My friend was driving his 2014 Tundra DC to work this morning and out of nowhere it started shaking and then stalled/died. He had to coast it to a safe spot to pull over. The truck has 230k miles on it and is regularly maintained. He had it towed to where we work and I was able to get a video of it cranking and trying to start. It's very noisy. We hooked a scan tool up to it and no codes. Any ideas of what could be going on with it?

Is that Rod knocking?? Inspect all cylinders for coolant/head gasket failure. Most likely cyl 7 or 8 where most common failures occur.

Edit: I'm no mechanic though, so its just my 2 cents.

 

She done, sound like a dropped/cracked valve. With the back firing out of the intake I would guess its a valve issue or a skipped timing chain.

 

Sounds like low compression and then there's the rattling when it kicks off. Valve train for sure. 230,000 miles isn't too bad.

 

That’s a weird sound. I have no idea what it could be, but please post if you ever get a diagnosis.

 

Sounds like a V7.

 

This is all kind of what I was thinking myself. Something definitely went bad in the top end.

I should mention as well, he has to pump the gas pedal to even get it to do what it's doing.

 

Fuel injectors?

 

Likely dropped a valve based on the most common failures reported here. Broken valve spring will cause the valve to fall down into the cylinder. Other potentials are timing chain issues due to failed tensioner. The hard start seems worse than single dropped valve honestly.
