Did you change the fuel hose in the tank when you changed the fuel pump. Internal leak on hose in tank,external leak on pressure line from tank, Bad pressure regulator, bad fuel pump. Take a piece of water hose about three feet long and stick it in fuel tank and hold it to your ear, have someone turn the key on, if you hear fuel squirting in tank, the hose is loose or cracked. Keep in mind that the fuel pump on runs for 2 seconds when you turn the key on without the engine running.

Do you have injector pulse durng initial cranking? you may have a bad cam shaft position sensor that "comes to life" when rpms are up. or an injector has a bad spray nozzle allowing fuel to flow into its cylinder,pulling the spark plugs and checking for any that may be "wet" or smell ''rich'' will help pin-point your problem.
