Engine is starting but it dies down after 5 seconds...

[MyX]

Guys, I need your help. I own a 2002, EFI, A/T Lancer. I encounter this problem only in the morning, or when I don't use the car for more than 12 hours. Also, my battery is new (barely 4 months old).

Here's the problem: the car starts with just one click, without a problem. However, after about 5 seconds, idling starts to drop until it dies down. Once I restart, I still need to step on the gas for about 30 to 45 sec for it to sustain proper idling. After that, I'm good to go. This problem does not happen when the engine is hot. This only happens in the morning, or when the car is not used for more than 10-12 hours.

Need your opinion on what I should check for when I bring this to a repair shop. Thanks in advance!

looks like a fuel filter problem (or anything related to it).

[chuaed]

to be sure have it checked... hirap na ma-tirik ka bigla sa daan tapos hindi na siya mag start...

possible problem:
1. may hangin/tubig sa fuel line
2. marumi na ang fuel filter

EGR valve?

i also have a lancer, 2001 mx, and had almost the same problem 2 months ago. engine starts one click then dies as i reach the corner (50 meters from the house). i had the fuel filter replaced and the mechanic found water in the filter. i think this was because i had not been filling up the gas tank lately (mahal na gaso kasi!) so water condensed in the tank. after i replaced the filter ok naman na siya. i may have to drain the gas tank later if it happens again.

^ sir how much did you spend for the fix?

[yebo]

^sorry i don't remember, kung mahal nagastos ko natandaan ko sana e hindi so mura lang ehehehehe! basta mura lang at fuel filter lang naman saka labor. wala pa 1k.

Maybe the function that increases idle on a cold start is defective. You mention that if it's warm, there's no problem. Definitely electrical.

ganun pala yun, that also happened with my 626 AT. sa morning lang mahirap mag start. pag mainit na one click na lang.

Sir, sa palagay ko ipa check mo yang fuel pump baka defective na kasi sabi mo nag shut off ang yng engine mo after 5 second na start.T saka sabi mo inaapakan mo pa ang yng gas pedal para maka sustain yng engine during start.Cge Good luck.

it's not the pump. kung pump yan di ka aandar in the first place.

I agree with speedyfix. Its not fuel pump. But it has to do with fuel supply to the engine. Filter as Yebo said could be the culprit.

I agree with speedyfix. Filter could be it as yebo said. You might want to have your EFI cleaned too. The problem basically has to do with fuel supply to the ignation chamber IMO.

[torque2006]

have your fuel lines and filter checked, and have your efi scanned.

Thank you sirs! Really appreciate all your inputs. Will go to a mechanic later and let you know what happens hopefully the fuel filter replacement and efi cleaning will do the trick.
