2000 Tundra will not start, any help would be appreciated

[Mart022]

My 2000 Tundra 4.7L (with 208,000mi) will not start. The starter is turning over but the engine is not. The starter was replaced about 1.5 years ago. The battery terminals have been cleaned and the battery seems strong.

The following link is a video of my truck to help in diagnosis.

Thank you for any help in diagnosing what is going on.

Wow, that sounds like you have no compression. Check your timing belt it may have snapped. Unfortunately, the 4.7L motor is interference so you may have valve damage. You can remove the passenger side timing cover pretty easy its 4 or 5 bolts i believe. Just remove your air intake hose and removing the serpentine belt helps but not required

Let me add you can also remove your oil cap and look at the cams and see if they move while you try to crank it. If they don't move then you know the belts broken

It's kind of hard to hear in the video, but it's either no compression (prob from broken t-belt) or the starter drive is not moving out and the starter is just spinning. I would first watch the drive belt to see if it moves when you're spinning it over. If so, then check the t-belt.
