Cold start - hard start

[theveed]

Question lang sa SR20 (or any efi car)

Pag cold start ko (meaning the car has been sitting for over 12 hrs or so) hard starting yung car, parang naubusan ng gas.

But if I leave the key sa "ON" for a few secs and depress the accelerator a couple of times, it starts fine.

After that, kahit ilang beses ko istart, one-click na sya.

Baket parang nawawala yung fuel sa fuel line pag coldstart and kailangan pa sya i-prime?

Chineck na fuel pressure ok naman

BTW, sa mga sumagot na sa ibang board, thanks, dont repost na hehe

kuya theeved.. suggest lng me po. kahit ako hindi nka esi kailangan talaga mag step ako ng gas basta 12 hours na nakaparada car ko. ganun talaga sakin .. sa manual ko naman step gas before start at okey din nman..

dont know sa esi baka pareho lng yata..
pero suggest lng po kuya. =)

faulty fuel pump? clogged fuel filter?

[theveed]

finchy: Honestly, lahat ng cars na nagamit ko eto lang ganun, except for the diesel benz. Once nastart na tong car, the rest of the day i can start it fine without depressing the pedal.

Pareng BB: Fuel filter OEM 1 month old. Fuel pump checked out OK sa casa as does the fuel pressure. Engine never hesitates when ran regardless of speed.

hmm maybe something wrong with the starting process..pero on cold starts lng..bad ground?

[theveed]

basta napa andar na yung engine kahit ilang beses istart one click lang.

di kaya sa starter yan or baka mahina battery mo?

[theveed]

Clavel: Starter I'm absolutely sure it's fine, as stated, it start a-ok any other occation with a single turn of the key. Pag matagal lang di nagamit sya ganun.

While I do have suspicions sa battery ko kasi mahina nadin the past few days, it's not the culprit kasi the car cranks fine and the previous owner told me that has been happening for quite a while (at least 3-4 months na in this case since I've had the car for 2+ months na).

di ba my life span din ang car battery natin ?

whatever its brand is ?

hula ko leaking fuel pump yan OR the line leading from the pump may leak. the fuel leaks back to the tank kaya empty yung fuel lines. when you switch to ON the fuel pump runs and fills the lines kaya ok, pero pag di pa umandar yung pump at start mo agad palyado kasi nga may hangin sa fuel lines. it could just be a small leak (sabi mo nga 12 hours or so na stop) kaya ok pa ang fuel pressure mo.

[theveed]

yebo: makes sense... di ko naisip uyn ah...

next question, san part ko titignan yung leak? after the filter na hoses etc?

di ko naisip yung sinabi mo hehe, sobrang logical...

Possible din leaking fuel pump din kasing amoy gas minsan yung car pag stop ka, yung smell nasamay lower door area ang amoy... hmmmm

[woulfe27]

dabid, maybe your battery needs a new car bwehehehe

[theveed]

hehehe gagu! :P

[yebo]

kuha ka lighter sindi mo then trace the fuel line. pag umapoy andun leak ehehehehe!

seriously, it could be anywhere. di ko alam mag-trace ng leak sa gas engine, puro diesel hawak ko dito kasi. same thing din sa diesel kung natutuyuan ng fuel sa lines most probably may leak. may gamit kami UV light kita agad ang diesel pag may leak (dapat syempre in the dark). ewan ko sa gasoline kung effective pero kung meron ka nung UV light na gamit pang-detect ng fake na pera pwede yun. dark room (or night time, or use a canvas/rain coat/etc to cover the area you are checking), turn On fuel pump then see under UV light. sa diesel it becomes light green color under UV, ewan ko for gasoline. or just follow your nose na lang siguro. pag wala sa lines baka sa pump na siguro yan.

ahhh.. galing naman.. me i dont know kasi nasa manual ko tapak talaga ako ng gas kapag 12 hrs nkaparad ang car ko.. parehas kami ni theeved problem ko sa corolla ko 1.3 carb
possible kaya may leaking na din ang fuel pump?

battery ko bago nman la pa mag 1 yr pa
2 months na oil filter
bago spark plugs
starter ok nman po

hayyy.. di ako makatulog n2

[buknoy2002]

ganito din problem ko

pa post naman kung ano naging solusyon ninyo

[finchy18]

sa manual ko sure talaga and2 naka lagay tapakan ang gas kapag long time nka parada sasakyan mo or cold engine.. post ko lng maya ang nsa manual ko.

[BoEinG_747]

next question, san part ko titignan yung leak? after the filter na hoses etc?

better cguro umpisahan mo sa tank ang pag tsek ng leak from tank to filter
then to fuel pump going to carb ..if ever sa fuel line ka may problem

tsek mo din lahat ang higpit ng hose clamp
or kung may defective ka na hose or pipe.

Possible din leaking fuel pump din kasing amoy gas minsan yung car pag stop ka, yung smell nasamay lower door area ang amoy... hmmmm

ganon din gawin mo sa Fuel Pump kung ano pwede higpitan doon
mag kakaroon naman ng mark minsan pag may leak ng fuel ..
unless kung mahina pa talaga ang leak
or sundan mo din nga ng pang amoy like yebo said

bro masarap yan ah..
pero kuya help me po saking prob

[theveed]

Boeing: Papacheck ko nalang kay Migs hehe... Hirap kapain kasi wlang tumutulo na fuel or anything under the car.

Just an update, I just bought a new battery over the weekend, yesterday and today was my first 2 "new starts". Yesterday, I tried starting it directly (no gas stepping, didn't leave the key in the "ON" position before starting), and same symptoms, but 2 tries lang start na (siguro mahina nadin talaga battery ko before).

Today naman, I left the key sa ON for like 3-4 secs (wearing seatbelt, taking off windshield sunshade), then started the car, it started right up to idling, although a "little" rough at first, had to give it a very small gas umphh for it to reach high idle.

But a lot better than before.

Still have to check for possible leak though due to the faint petrol smell sometimes outside the car near the rear.
