We all have some ISSUES. The more meaningful subject line would bring your thread more attention.
Now let us go back to your problems. Have you checked the compression?
I would also make sure that the timing belt did not jump a tooth. Open side covers and make sure that all marks on sprockets are there where they suppose to be.

Good luck,
Sam
