Intermittent Start - Civic FD

[Renzokuken]

i have had that experience in my non-honda cars.
it's probably the starter solenoid beside the starter. if it is, replace it, po. it costs a pretty penny, but nothing short, will improve on your experience.
it's pretty de cajon. one can do it, if one knows how. but the tambay mekanikos beside the auto parts store, should be able do do it faster, even with one eye closed.
good luck.

Around how much will it cost me?
