Hey Guys,

its been a while im facing starting issues with my renault megane 2 , randomly the car cranks but doesnt start:

i have changed both crankshaft and camshaft sensors but no luck .

please let me know your suggestions , what might cause this problem since i want to avoid going to the dealer ending up paying a huge bill.

i would prefer to ask the mechanic to try your suggestions hopefully any would solve this issue

Thanks in advance
