Lancer starting problem

[QQDreamer]

Hi all, I'm driving lancer ex 1.5. Lately I face issue when starting the car. Occasionally, the car will take quite awhile to start

 

Previously this happen before, at times the car will crank but it takes a few second to start and when starting, the power seems weak. After a few time, the battery went dead.

 

After which i change my battery and after 6 months, this happens again. Long cranking before the car start up.

 

Any idea if its weak battery, faulty fuel pump, faulty injector or just a dirty fuel filter

 

Thanks

 

sounds like your fuel pump and filter needs attention. have you change it before? if not its about time to.
