Hi:
If it's poping throught the intake or exhaust and won't start, the timing is out. Check out the "Popular Cite Links" on this page, and go to "Timing Belt MArks." Put in your vehicle's information and it will bring up a drawing of how you should have set the timing. Make sure it's correct.
If you have any other questions, let me know. However, based on your description, it sounds out of time.
Joe
