I have recently replaced the fuel tank, fuel pump, fuel filter, complete tune up, spark plugs, wires, distributor cap and rotor. Before I did all this I replaced fuel tank fuel filter fuel pump. Complete tune up. What should I do?

Check if the injectors are pulsing and also if the fuel pressure is within specs-

If the injectors are pulsing it should be injecting fuel into the cylinders-you sure its not clogged-

ALL injectors should have constant power when the key is on. What is the fuel pressure?
