I am residing in UAE and it hot summer season here( 45 degree +). I have Hyundai Sonata 2012 model car. I am using this car for last 7 months. It was running fine till this summer. I am noticing starting problems often. I usually drives in high traffic road for 1 hour daily. I drove 25 kms and stopped at a parking lot & turned off engine today. Then i decided to change the parking lot and tried to start the car. Its not starting(Engine cranks, then stops. seems weak battery, but battery indicator shows green and healthy). This happened last week as well. But when i started it after 8 hrs, it worked.Please suggest what might be the actual problem.
I'll bet it's Crankshaft Position Sensor. It's a one bolt sensor beside the timing belt. All you have to do, go buy a used part for fraction of the cost. You will get an engine check after this and it will say "crankshaft position sensor" but you can clear it when car is turned off.
Crankshaft position sensor cuts fuel by sending wrong info to ECU. Disclaimer: I'm not a mechanic but these are things I learned on my own.
