Car sitting a long time unused and the car battery is discharged.
Tried to start the car multiple times.
Starter motor is cranking but the engine won't start.
There is fuel in the Cylinders.
Check Fuses, disconnect fuel pump.
Press gas pedal to the floor and try to start.
When you press the gas to the floor while starting the car Computer - ECU enters into clear-flood mode.
It fires the spark plugs and ignition coils but it won't start the fuel injectors.
To be sure, you can disable the fuel injectors - remove the fuel pump fuse as shown - on your car the fuel pump fuse location may be different.
Check spark plugs if they are wet with petrol and use a small torch to clear fuel - CAUTION if you do this, let the spark plugs cool down before you touch them. Or just use new spark plugs!
If the engine smells like fuel and spark plugs are wet, let it sit to evaporate or crank the engine while the fuel pump is disabled and spark plugs are removed - open spark plug wells.

Am schimbat pe masina bujii bobine baterie clapeta admisie distributie senzori, tot
@@petruburchel si incearca sa porneasca sau nu se aude nimic?
My car does the same thing polo 1.2 9n series... it usually happened when I drove for a while, parked and then the next start will be series of cranking before it will eventually start.
From your video I think I will hold down the gas pedal before starting the engine when it happens again.
Thanks this is really helpful.
I wish I did the pedal and crank first. Car was sitting a long time so battery was dead. Charged the battery but engine was already done.
Probably 1 crank and charge before going further would fix it 99% times when it's sitting a long time.
In your case, if you just let it sit overnight or few days, I would check the battery voltage during cranks.
Could be anything, best is to scan it with an obd2 interface.
Its very good but my 2001 model volkswagen polo car show light but not start
I have the same problem with Seat Ibiza 1.2 12V from 2010.. at first car couldnt turned on. Showed EPC and Engine sign.. i have changed spark plug and new battery then the same noise as you.. i’ve removed the spark plug and the was fuel at bottom of all spark plug.. i think there is too much fu in engine.. any lesson how to flood fuel from engine ??
Try like in the video - remove and clean spark plugs then try to start the engine with the spark plugs removed so the engine cranks but it doesn't start, any fuel in the pistons will come out thru the empty spark plug holes and then clean the spark plugs put them broken try to start the engine by pressing the gospel all the way to the floor when you start it. Sorry about the formatting of the text - voice typing
Excellent
Mine does it randomly. Usually starts okay first thing in the morning okay. Usually has issues after sitting for 5-15 minutes. After cranking for 1-2 minutes it seems to start coming back one cylinder at a time.
Did you figure out the problem ? Mine does the same , can't figure out the problem
I got this same problem, and had it for years but lately has happened almost every week my obd scanner does not show any faults, does anyone know what is the problem. I have changed egr, spark plugs and ignition coils
I haven't sorted the issue out. Took it in to get repaired, and they put in new spark plugs and an air cleaner. It worked well for about a month, and then started playing up again. I modified how I start it ( turn on ignition and wait until I hear the fuel pump stop ((guessing what the noise is)) and then crank it, no accelerator). This worked okay for a few months, but now it is back to its old self. Probably about 50% of the time it won't start first time.
Hi I have the same problem. Car use to start one swing it start but now engine cranks but take long to start got new batterie. It still struggling to start.. Polo classic 2003 1.4 tdi.3 Cylinder What can be the problem
Same problem . It happens ever winter and i have to call the mechanic or the break down people . And they day the same thing . Its a cold start .
very useful 👌
Got the same problem, have replaced spark plugs, battery and filters. Fixed it once but it keeps happening at random through the half year ive owned it. Any ideas?
Does it try to start when you set the ignition to start? You hear the starter motor spinning trying to start the engine?
Salut! Modelul meu porneste uneori greu si merge cam in 2 clindrii, trage greu si nu trece de 4000rpm. In general porneste bine, dar am observat ca si atunci cand e ok masina, la solicitare puternica miroase putin a combustibil nears :) Ai idee ce problema au motoarele astea in privinta pornirii? Au probleme cu valvele? O fi ceva electric?
Obd2 scan - daca are misfire, ecel mai probabil 1 sau mai multe bobine de inductie.
Cred ca nu am facut video despre asta dar in clipul asta trebuie sa le fi aratat. Daca vezi ca e vreuna care are umflaturi sau arata diferit, schimb-o sau schimba-le pe toate 3-4 depinde de motor.
@@IONHowToMersi mult de raspuns. Am testat bobinele si am simtit ca o iau razna, toate functioneaza corespunzator. Motorul tot merge aiurea, de parca e in doua pistoane in loc de 3 in cazul meu (in functie de cum porneste - daca porneste la sfert merge rotund ; daca nu porneste la sfert - merge inganat). Astazi am inceput sa deconectez bobinele in timp ce mergea motorul sa vad daca e vreo diferenta intre modul in care merge motorul... si aparent toate pistoanele sunt la fel de "cu viata". Am inteles ca la motorizarea 1.2 se strica des bujiile si bobinele. Bujiile le-am schimbat, bobinele sunt aparent bune si nu stiu daca sa le schimb in contextul asta. Am avut o eroare de senzor ax came, pe care am rezolvat-o schimband senzorul, insa motorul merge la fel. Pe net am vazut ca mecanicii rusi spun ca la motoarele 1.2 se duc valvele super usor, se prajesc de la missfires, care au loc frecvent in motor. Cu asta ma confrunt, missfires pe care nu reusesc sa le identific. Am verificat toate cablajele care dau scanteie, n-am erori pe senzorul MAF, injectoarele merg cum trebuie. Problema e ca am amestec prea bogat si de la asta, inainte sa am eu masina, la fostul proprietar, s-a imbatat si catalizatorul :) Efectiv ultimul lucru care imi mai ramane e sa ii schimb distributia si apoi sa ii schimb valvele si catalizatorul... totusi la mine proglema e intermitenta, la unele porniri merge motorul rotund, la altele nu :) Habar nu am ce are.
@@edwardadelin689 Eu cand am avut probleme cum descrii tu a fost mereu de la bobine. Aas am un video cu bobine acum mi-am adus aminte.
Eu cred ca trebuie sa incerci sa le schimbi pe toate.
Daca vrei sa fii sigur asa am facut eu prima oara:
Vezi cu vagcom engine pe ce cilindru e misfire si notezi. Dupa dai clear.
Muti bobinele intre ele toate, 1 la 3, 3 la 2 si 2 la 1 sau cum vrei tu.
Dai clear din nou daca e nevoie si pornesti - astepti codul. Daca s-a mutat misfire la alt cilindru e de la bobine sigur.
Poate sa fie si senzorii o2 lambda pre cat si post cat. E printre prinele video-uri pe canalul asta.
Coolant temperature sensor.
Clapeta de acceleratie
Bujiile daca sunt ude e misfire.
Poate sa fie si injectoare + pompa benzina sau chiar filtrul de benzina imbacsit. L-am schimbat si cred ca am facut video si cu ala.
Verifica/schimba intai bobinele.
Mersi mult pentru raspuns. Aprecieri pentru canal. O sa ma uit la primul clip, inca nu il vazusem. Numai bine. Revin cu comentariu cand rezolv problema poate ajuta si pe altcineva. Tinand cont ca problema la mine e intermitenta, voi incepe cum ai zis cu bobinele. Sper sa fie ele, cu toate ca la teste pareau toate bune. Numai bine

I have the same problem with my vw polo 1.4 2010 model. The car cranks when standing in the sun or when it's hot but starts after a while.
Same problem with me whenever i start my car in the morning it won't start and if it got started get warms then no issue it starts properly only happens when it stands 3-4 hours
Plz sir tell me the solution
Solve this??
@@buntrockstudios yes solved but the issue was in my head gas kit and valve the coolant comes on the cylinder so so spark was not generating after fixing issue its been 3 months i am completely satisfied and driving my car without any issues
@@ishan4288 is your car a 3 cylinder polo 9n I've got this exact problem will take it in to the garage soon I'm just carrying a jump starter around for the time being
@@buntrockstudios yes bro my polo is 3 cylinder this things only happens when ur car is standing for a long hour and then u try to start it keeps on cranking if u got started and then switch off the ignition and then try to start it will start but the only problem facing after long hour car stands then only the starting issue came up
Hi need help here. Changed clutch on 1.2 polo 2010 and now car is not starting
hi i need help with my car it is a golf mk3 1.4 cl . i was diagnosing a problem and disconnected battery and i believe i left the key on ignition while battery was disconnected and so i believe key code disapear. the car was working just fine but now wont start. crancks but does not start. can you please tell me what could be the problem and how i can program a new key code. i have 2 keys but just 1 has the key code the other is just a normal key that could never start the car.
I don't know, try to ask on forums related to your model.
If you call a mechanic / car key maker+programmer, they will fix it for you as long as you show proof of ownership afaik.
I have almost the same problem but my car stars, but cranks a lot when i start th eingine, and after the ingine is on the car is totally normal work great, i want the cranking go away..., i have change gasoline valve, gas filter , ingine filter, plz help
Scan for obd2 error codes.
Could be anything. Misfire / ignition, fuel delivery, coolant temp sensor.
If the car is at normal temp. and you stop the engine does it start normal if you try to start it again?
Wait so what's the problem? Mine had the same problem, but why does this happen?
Probably it all started because the battery was too low. Engine got flooded with petrol as I was cranking it. Not sure if this was it.
Has Vw Passat tdi 2.0
P7 2011model ..when I start it cranks but engine not start ..but some time after 30 min it get start ..can’t find reason !!..it occurs many time ..can any one tell why
Does tdi injectors working fine enough? Check this out first. Fuel pump ok, etc etc.
My polo 1.4 says clochichi clochichi doesn't start please help me, I have replaced spark plugs and Coils but says clochichi clochichi please
Get it scanned with an obd2 scanner. It could be anything.
bky engine is that the same
Deci toata problema se rezolva cu apasarea pedalei de acceleratie?
Poate ar fi fost de ajuns dupa ce cureti/usuci bujiile.
Brother what happens if the car turns on and makes a humming sound but does not start
Belt (starter) is spinning when trying to start?
My car is doing the same
Where is the fuel pump fuse
If not in the video, check guides online for each fuse. Wanted to write an article about it, maybe I did
Its not startinggg and its Saturday nighttttt((
Remove the fuse of the injectors
I think I removed the fuse of the fuel pump
