Possibly a plugged fuel filter

you need to take it to a shop,and have them properly diagnose it they can see and hear what its doing we on here cant, we base our answers on what information the person gives us,you still have a problem with it some where,good luck with it.
The year and make of your car would help a lot here.

How was it running before you changed the pump. Is it the air filter you changed or the fuel filter... email cf_fills@yahoo.com
it sounds like a bad ignition module. the way to check this is to pull a plug wire, insert a spark plug and ground the plug shell. then have some one crank the engine over, and if you see a nice blue spark, the you still have fuel system issues. if no blue spark, then you have ignition issues.



fuel system issues can include a bad fuel pump relay, and bad fuel pressure regulator.
did you try bleeding the air out of the lines?
