Changed with new. Went to start and would run on 2 cylinders. Since then have replaced Plugs cap rotor, computer (Had a bad repair job on it). Swapped out ignitor. New coil. When the key is turned it will run on its own for 2 or 3 revolutions then shut down. When you turn the key again it will just turn over. Has a slight smell of gas after that. Checked injectors and they are pulsing. What could it be?

Do you

Check the fuel pressure if its within specs though the fuel pump is new-there's such thing as manufacturer defects-if its not a fuel pressure problem check for an ignition spark and let us know-
