Fuel Pump?

My car has been acting a bit weird lately. When I would start it up, it would take 2-3 more seconds for it to start. Boost wouldnt work properly, and it dies sometimes at idle. At high RPMs, it sounds like the engine knocks once and awhile.

I first replaced the MAF sensor, then the TPS, and the spark plugs. New fuel filter too. Could it be the lack of fuel pressure that is creating these problems?

{EDIT} Also, how much would it cost to replace the pump?
 
Do some diagnostic work before you throw more parts at it. Are you getting a check engine light? Have you scanned for codes? Do you hear the fuel pump come on before you start the car? What is the fuel pressure on the rail? When you say the boost does not work properly what do you mean?
