Run a compression test. Be perfectly sure you have the valves spot on. When the exhaust is open you can adjust the intake and visa versa. When done right the pushrod will have some drag.

By drag do you mean resistance to turning?

Ok, try to reset the valves. This time use an up and down motion on the pushrods instead of twisting. When you can no longer move the pushrod up and down ypu're at zero lash. Add 1/2 turn and you're good to go.

Check the injectors by unbolting the fuel rail from the manifold and lifting everything away from the manifold. Have someone turn the key to on but not start. There should be no leaking. If there is you have a stuck njector(s)

Good luck
