Things to solve a cold start issue?

[PamelaAsistio]

Hello tsikoteers, just wanna know if the starter can be a major reason of cold start problem? Sorry if you find this a non-sense question, the reason I asked this because our car is only experiencing hard starting at first start, but when the car finally starts, wala na pong problema sa maghapon even if you on and off the engine, one click na lang.

- Carb was already properly overhauled in kamuning and replaced complete set of carb kit not just the o-rings
- OEM magnetic fuel valve was also replaced
- NGK plugs were just replaced last May
- Fuel filter is also new.

Is there any other things to consider to finally solve a cold start issue?

Ride is honda 92 / PH12 engine. Any response will be highly appreciated. TIA

before po nyo start ang engine paki check po ung engine oil ninyo (mas maganda po kung nag overnight parking kayo then sa umaga para nag settle down ung langis).

kung malapot po ang langis need po yan i-circulate kaya po maingay ang cold start.



Possible naman din po na malapit ng bumigay ang battery ninyo, pa-check nyo na din po ito sa mga battery shops normally libre naman ang pag check nila.

Sir, the battery and alternator were already checked in a nearby motolite shop and both are still in good condition. Although, when we got the car last december, yung battery po na nakalagay has no labels or whatsoever, basta kulay black lang casing nya.

could be an old battery that is already near death. ok na siya nung pina-check mo sa motolite shop kasi nga nag-start na yung car at na-charge na siya, but overnight it might be losing charge.

ano ba gamit nyan ph12 manual fuel pump or electronic?? yan muna check mo

[Manilablock]

nung magpalit ka ba ng fuel filter na-drain din ba ung fuel tank mo?

possible din na madumi ung fuel sa loob ng tank, tignan mo din ung fuel cap kung meron moist.

try mo magpakarga sa ibang gas station ung alam mong hindi binabaha

Sorry sir, not sure if its electronic or manual :-) Although the car is a bit old, so I guess its the latter one.

Did your hard-1st-startup-in-the-morning happened after you had your carburetor overhauled? If yes, your mechanic must have messed up the adjustment of the fuel float or the replacement float he installed (fr the new repair kit) has a different setting. Straying away from the factory-set fuel float adjustment will make your gasoline evaporate more than usual (in the carb fuel chamber) during overnight parking. This will make the carb fuel-starved in the morning, hence, the hard 1st start-up

as experienced, choke mechanism ng carb ang may problema. have it check.

after everything has checked out ok, you might want to check the starter itself. the starter solenoid might be sticking or have poor electrical contact. or the starter bushings might be in need of replacement.
another possibility is, your hi tension cables might be leaking electricity and are in need of replacement. (try starting your cold engine in good darkness and see if it shows minute sparks...)
i hate intermitttents...

but the low fuel-in-the-carb theory above, seems a very good choice.. we used to play with that a lot in our younger days.. we were aiming to maximize km per li, back when gas was 8 kesos a liter..

This seems to make sense. When I start the car this morning, it just cranks and the lights get dimmed and the horn is not that loud. So, I had it serviced by a nearby mechanic and told us that the battery is already busted.
Will update you after we got a new battery within this week. Were keeping our fingers crossed that its only the battery thats causing the cold start issue.

Dapat pati charging nung alternator ma-check.

Just encountered intermittent starting problem .Three weeks na ko pinahirapan mag trace. Nakakahiya magpatulak.

Loose thread Ground Terminal bolt pala sa casing ng Starter ang problem.

Hi, just to give an update. We already bought a new enduro battery but still the problem exist. Nung inistart po namin yung car ay inabot parin until 5 tries bago tuluyang umistart. We brought it to a nearby mechanic pero kahit po sya parang hinde alam whats the real reason behind the cold start because everytime na dinadala namin sa talyer yung car ay one click po lagi...even he on and off the engine at kahit pa patayin nya ng more than 4 hrs then pag inistart sa hapon ay one click pa rin.

We decided na hinde na muna ipagalaw sa mechanic kasi kahit sya ay hinde nya masabi kung ano dahilan and what to check dahil in good condition na po yung auto pag nasa talyer na nya.

We had an experience in our other car before but its the other way around...laging one click lang sya pero pag uminit na ang engine at inoff, hard starting na...and it turns out na busted na yung coil. So after we replaced it with a new one, problem solved.

But in our honda's case, kabaligtaran naman po ang nangyayari, thats why we are a bit puzzled kung bakit sa 1st start lang ang hard starting, pero once na umistart na ay wala nang problem the whole day. Hopefully, our gurus here could enlighten us how to finally solve the issue, every morning po kasi I need to allot 10 mins bago umalis dahil hinde agad umi-start yung car. TIA

Maybe yes,we have had that problem before,to check it ,our mechanic make a choke attempt twice on the carb,if it start then palinisis mo carb or change your fuel pump .hth

Your problem seems to be fuel - related. Your electricals seem to be working ok. With these carb - equipped engines trouble shooting a hard start usually centers on the fuel supply (carb, fuel filter, fuel pump), the electrical supply (contact point & condenser/igniter, HTW, sparkplug, ignition coil, voltage reg,relays) & the ENGINE TIMING...

Sir, our carb was just overhauled and replaced the complete repair kit by carb experts in kamuning last june only. They were also the one who handled our other car's carb, kaya trusted na po namin at tested na pulido ang gawa nila. Fuel filter is also new
