You`ve pulled the timing cover and the gears are on correctly? It`s easy to get them off a few teeth without even realizing that you`re using the wrong indexes. It wasn`t long ago when I was at a friends house visiting. He had his engine on the stand and mostly assembled. I looked at the timing chain and he had installed using the wrong indicators. I had done the same thing and the car was acting like yours. The crank gear is easy to position wrong because people want to use the large mark that appears on the hub of the gear just above the woodruff key and not the small mark that appears on the tooth of the gear. You might check yours to see if it is done this way. Here`s a couple pics of the mark I used and then the corrected marks.
