Yes. It must be turned very slowly and by hand. The crankshaft is optimal but hard to reach, especially while watching the IP, valve rockers, and crank angle. I have had good luck turning the engine using the nut on the power steering pump (assumes correct belt tension).

There are very specific procedures and if the mechanic does not know them then he is blowing smoke when he tells you he has done the job right in the past. There is no way he can turn the engine with the starter and get an accurate idea of when fuel delivery starts, NOT when it spurts out. He needs to be turning the engine with a bar and socket on the crankshaft so he can see exactly when fuel delivery starts. Sounds like you need a mechanic that has a clue what he is doing instead of a parts replacer doing a bunch of guesswork.
