I tried to start my volvo s90 the other day and it cranks but wont start. When you try to start it in the morning it sounds like something is not moving freely. It tries to crank but sounds like some pulley or something is holding it up. I checked the power steering fluid and its so low that it is not even registering on the dipstick. I wanted to know if your power steering fluid can be so low that it would prevent my car from starting.

 

I would say no. If you post a video somewhere that may help us.

The AC compressor is the strongest thing down there, however, the starter will usually break a belt before it allows something to stop it.

When was the last time you did a timing belt job?
