Re did the timing replace the timing belt and cranked it had it fire once and popped the turbo charge pipe off. It wasn't on very tight after that it won't start and had no compression now so I think it may be lawn mower syndrome from trying to start it after the belt was replaced.

If it's too easy, or if it won't budge at all, you've got some mechanical damage in there. It could be the timing. Take off the outer timing belt cover and give it a good look. Good luck troubleshooting.

The engine cranks completely fine stiff enough not to have me worried it doesn't notch at all or stuck in any position

This would be a strange coincidence, but worth a quick check. You say you have fuel. Have you pressed the schrader valve and it produced a good hearty squirt?
I'm asking because I assumed I had fuel to the fuel rail in my 93 850 when I tried to start it in October after not running it since July. In July it ran fine, starting instantly as always and with no hesitation or other symptoms that might indicate a bad fuel pump. But in October, with the outside temperature colder, it wouldn't start.There was some fuel getting to the fuel rail when I checked the Schrader.
Anyway, I had a spare fuel pump,I changed it out and it fired right up.
You might check that the schrader is releasing a good hearty squirt, just to be sure.
Good luck.

I would get a compression gauge and check compression. I have seen cars start and run with several valves bent a little.

How many miles ago was the head work done?

I have never heard of a wheel splash guard getting caught in the belt area.

Test this first (one teaspoon of oil in each cylinder) then check compression.

Put oil in the spark plug wells had it fire on 2 cylinders for a split second had compression and now it will not start again still make the whirring like it has no compression

Time to break out the gauge

pretty sure i have a bent valve was checking the timing again and the intake sproket would only go so far with out a lot of force. sadly it is time for it to go back to the shop to get the warranty on the part good thing is it was done not even 140 miles ago
