740 not starting after timing belt change

[dalail4m3r]

Hello fellow petrolheads. I drive a 740 from '88 with the b230f engine.

I changed the timing belt with a friend of mine. Afterwards I tried to start the engine twice which didn't work. I've never heard a sound like this before, like the engine was trying to turn but couldn't. After checking every step we noticed that the crankshaft bolt wasn't tightened properly. We used only 60nm(44lb ft), although it needs another 60 degrees of turning. Bodged it. Well, the engine is non-interference, but I don't know if this caused any damage.

As I'm 23 and only mildly experienced, I greatly appreciate any help on how to proceed. I really do like my car

Did you get your Volvo running? I am having exact problem. 1993 Volvo 940 same engine. I have had it in shop and they invested over $20,000 in software and test equipment on it. It was running until I went to change to he dang timing belt. Well ordered special crank stabilizer tool to mount correctly and remove in same sense. Every component is new under the hood lest the AC compressor. I am from Texas. That Volvo is good year. Don't give up on it.

Confused as to why software would be required to sort out a cam timing belt issue. Not sure that expensive software would even be of use with your car. Your problem is directly related to the timing belt not being timed correctly.
