My i30 just stalled at a red light. It did restart, but was idling extremely weakly and poorly. The gas pedal did not effect the idle at all. I stopped the engine and restarted it this way a few times, only to have the same very weak idle. At this point the car will no longer catch at all.

I figure that the problem is either the spark or the fuel delivery, given that the starter cranks without a problem. Here are some related facts that may be of note:

• I changed the spark plugs only last year
• I changed the camshaft position sensor a little over a year ago (after not starting at times, and engine code)
• The car has been taking one or two more cranks to start lately, but it does feel out of the blue
• no code has been tripped
• I had little fuel in the car. it was above 0 though, and I added more fuel without effect

Any ideas would be greatly appreciated! The car is currently parked on the side of the road.

 

Did you figure out whst the issue is... it may help others ..
i would suggest clean the ait intake and THrottle body

 

The problem was the fuel pump. It was very easy to diagnose since, when I turned the key to the on positions, there was no "whine" heard from the pump. It was also very easy to change!

 

Thank you for sharing that solution with us.
