My cultus is 2011 model efi 52000 kms done, i am facing this problem for last 15 days or so, the car starts fine most of the time within 1st self but problem is after i drive it for half an hour and stop somewhere and take a break for 20-30 mins, after that car does not start, it does not even take self (gari ko start karne ki koshish karo to fan on hota ha par engine start nahi hota or koi sound he nahi ata self lagta he nahi).
PS: Fuel pump awaz kar raha ha pichlay aik mahinay se seeti ki awaz ati har waqt or mene 5s dealer se b pocha ha unho ne b fuel pump replace ka kaha tha par kaha tha ke filhal aise he chalao. But car does not start on CNG too, when i try it pressing the CNG converter button for few seconds it comes to CNG but dont take self. so what could be the problem???
PS: After i change it to CNG and then turn the switch off, phir start karta hu to hojati ha start wohi petrol pe. Aisa do baar to huwa ha ke start hogayi ha, akhir problem kia ho sakti ha
SOLUTION: battery was the culprit in this issue, i changed it to AGS 50 AMP battery bought it for 4400, old battery sold for 800 (it was phoenix battery of 50 AMP which completed its 25th month) so i paid only 3500 Rs. and it has 6 months warranty. Now the car self works more rapidly and there is no problem of starting even when the car is hot.
PS: the terminals of the car which attach to the battery terminal are weak i guess, its factory fitted i will changed them to in near future, one of them sometimes get loose.
