My passat still wont start

I had the head gasket and timing belt replaced about a month ago. It gradually became harder and harder to start to where now it only starts with ether. I took it to a mechanic to have static and dynamic timing checked. IP timing was off and he corrected that but it still will not start without ether but once it is started it runs fine. He is going to run a compression test next. What else can be done to trouble shoot. I need to get this car running ASAP.

keep using ether and you won`t have to worry about starting it!!!

Sounds like classic symtom of crank sprocket D slot is worn. Make sure you get a new bolt when checking as they are one time use.

Do we have to pull the sprocket off to check it. Or will it be loose or what? I've heard of this once before.

Yes, you will have to pull it to check it.

Since it was gradually getting harder to start, I'd also suggest the crank sprocket.
