Fuel filter or Fuel pump :(

[tyrone_yaris]

Hi,

My car (Toyota Vitz 2007) hesitates for a few seconds like its choking or struggling to stay running, after I start it in the mornings or in the late evenings when the car has been parked for a long time say about 7-8 hours. It then runs normal but the mileage also sucks.

Could it be the fuel filter that needs replacement. I dont want to spend mega bucks and go for the fuel pump right away at this moment.

What do you guys suggest?

Thanks
