SAT FOR SEVERAL YEARS. WHEN WENT TO START BAD FUEL PUMP.

1990 Mazda b2600 • 265,000 miles

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?

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-

Oops forgot. Fuel press was 45+ changed press regulator. Coil, cap, rotor, wires new. Ignitor known to be good
