starts and runs for like a split second it revs a little to about 3k and shuts off its a manual. i just did the head gasket. im thinking maybe timing? i can get it to kinda stay on if i keep revving it but once i get off the gas it dies. i did put the motor at TDC and lined up the disty lines and put it back together and tryed to put it in the same markings it was before that the nut made a mark on the distributor.
