Changed timing belt, now won't start

I hope you can post photos, it would be interesting...While I do not favor using the tool hole at all for removing the nut, I would think that to tighten the nut, you could rotate the shaft 360 degrees and contact the tool from the other direction...

My concern is about where on the crankshaft the tool establishes contact...Is it against a counterweight, which is probably OK, or is it against the crank-throw on the connecting rod bearing?...I would not like that, it could damage the bearing...In my mind I feel that Volvo did not intend this hole for holding the shaft while the nut is removed, I think that they meant it only as a location point for timing purposes...

Not sure if it will work for clockwise. I'll try it on the weekend. This is what we should be using to hold the crank. Part number is 9995433 It's in Vadis under Oil pump removal. Also I've included a photo of how the (incorrect) tool would be used and also a makeshift flat bar in the starter hole for preventing clockwise rotation:

"Timberwolf, I think you might want to take another stab at setting the timing correctly. I can imagine that this is not exactly what you want to hear, but better safe than sorry. Now, the question is, how do you go about finding the crank mark???" - I did locate the mark on the crank gear (tiny tiny v notch at the bottom of a valley on the inside of the gear) & there are two marks on the block, one large and one small. At TDC it's pretty close to the smaller mark, but not right on it. It has been running flawlessly for the past 2 weeks. I'm not going to temp fate and change anything right now. Maybe I screwed up and got lucky at the same time. Who knows, but at least it runs now.

OK, I have XC90 2.5t and went to adjust timing as I was getting cam sensor and fuel pressure sensor codes, ran fine, but codes were annoying. OK, moved CVVT pulleys one tooth to cure problem, now car will not start, strange, what does one tooth make for a non start issue? No doubt the mark on hub to engine is impossible to see, but I am sure it is closer now than it was when it ran fine. Any ideas.

What were the codes?

I am not sure, not near the car rf diagnostics, just remember it was a can sensor code, and fuel pressure sensor code, but engine ran great. 110 rings a bell.
