I have never had to bleed the air out to make the vehicle start after replacing the fuel pump. You should have the fuel pressure checked to see if you are getting 41 to 47 psi when you cycle the key several times while checking the pressure.

If you do not get the specified pressure then you got the wrong fuel pump or a defective one. A certified mechanic could help you find what's wrong or replace the fuel pump if necessary.
