Too much belt tension.


Back the tensioner off a just a bit.
Rotate the engine clockwise by hand a few times.
Retension the belt.
It should come back around.

It may not once belt frays, the extra lump there will stop it from re-aligning.

Again no magic there, probably too much tension at the start. You are at the end of a long stream of hundreds who do that. You just can't get your head around how loose they are supposed to be. The more tension you add the more friction you have to walk sideways up or down a pulley. They minimize physical guides because the edge bumping again produces the fraying that makes belt fail.

A worn pulley bearing can let pulley lean slightly to move belt.

On the tensioner there is a tab that goes into a opening on the plate it's mounted to, is the tab located in the opening?

If so I would pull the motor mount and belt side cover and see what's going on.

Did you pull the engine front cover plate that the motor mounts bolts to?
The accessory idler mounts to it. It's not that bad to pull.
I thnk a straight line of sight down the belt is needed.
Sounds like you may have already.
Crank pulley was not flipped? Is the key in the crank aligned with the pulley? Perhaps the key bound up the pulley from going all the way on?

The belts walk with too much tension, whether on standard zetec or SVT, common issue and hundreds of posts about it. If the belt is visibly frayed in any way whatsoever you must have a new belt. Appears to be from the difference in belt polish on the top side in the pic. The pulley edge frays the belt bottom to fail early.

A misworn to lose the crown pulley, or loose pulley bearing can do it, the tilt allows belt to ride off end of sprocket.

You do NOT need any physical side guides on belts AT ALL to keep them running true. I ran them for 30 years in the printing industry at high rates of speed and no guides at all, the pulley is either low in middle of the OD surface or high depending on design, as long as not worn the belt will stay in place forever like that. On these the plastic pulleys are low, take two parts and butt the outsides together to see it. Thinking the metal sprockets may be straight but you only need a few 'director' pulleys in a system to track a belt straight-they do not all have to be crowned one way or the other.
