thanks sa mga replies, i'll have a hard time explaining this to my dad. old habit nya talaga!!! he also pumps the gas pedal before starting our EFI car plus if it doesn't start he quickly follows up another attempt.

btw, when an EFI car doesn't start on an attempt, i can hear a sound of something being pumped for a few seconds, is that fuel being pumped? i normally wait for the sound to stop before making another attempt
