2000 v6 wont start after timing belt replaced
 

after a few rotations by hand and all marks still lining up just as they were before the belt was installed it now starts for 10 seconds (at best) then dies off. all grounds seem to be fine, cam & crank sensor connected, and no check engine light when it does run for the short amount of time that i can get it to run for. when any throttle is applied it shuts down. really at a loss and any help would be greatly appreciated.
