2001 Kia Rio Question: car won't always start right away

the car will backfire and whine when trying to start it. then the engine light will come on. it was towed to a shop and they put it on their machine and no codes are coming up. they are able to start it all the time. -
Answer 1
The check engine light could come on when the engine stalls and not set a code, but if the light is on while it's running, then there should be a code. I would go down to the shop and start the vehicle a few times with the mechanic who looked at it. Try to get it to happen and see if the light is on when it is running. -
Answer 2
check misfiring. i mean the order of firing in the 4 cylinders.. but sure the spark plugs are in good conditions and in the right place of order. -
