Need help wont start diagnosis

Past week the car has been stopping due to cam sensor code, locAl tuning shop suggest your cams are jumping or something along the lines

Car died due to cam sensor again, I took off the cam cover and saw the belt was loose, so before starting the car I took 2 wrenches to move the gears to tdc to make sure they line up

Upon doing this I heard a click like it jumped but the belt still moved, it did it twice

Cams were lined up tdc tried starting the car and now it just spins freely like its not building compression, everything spins but wont start. Even the turbo will not move

Also here like a release of air like a piff sound

Any ideas? Tomorrow going to realign everything and hope its good. Will do a compression test as well. Maybe a boost leak test to see if valves hold air

I'd say your timimpng is off now and you're not making any compression. Pull the front cover and check you timing marks and belt. Depending on the miles I would probably just put a new belt on, with tensioner and pullies. If you're not accustom to doing this sort of work on a car have that tuning shop do it.

I definitely would not have tried to start it, take the timing cover off and inspect everything.

You need to stop and take the car to a shop or get someone who knows what they are doing. Using wrenches to move the cams.... This was just a fail move to begin with. Chances are your belt jumped a tooth and you now have bent valves. Be ready for a head rebuild and a timing belt job at the least. Worst case, you dropped a valve and are going to need a full engine rebuild.

How do you know you didnt bend a valve? Also you should figure out why it jumped, your tensioner might be going bad.

Yah my tensioner blew its guts out and i skipped one tooth. That bent almost all my intake valves, and there was no way I could tell they where bent till the head was disassembled.
