I have an 09 Kia Optima. Sometimes when I go to start my car it will not start. I have power to everything. The radio comes on, all the lights on my dash light up like normal, and if the air or heat is on it will blow. I have to keep trying until it finally starts. I have been to a mechanic who said all of the mechanical parts are working fine so he replaced a bunch of connections. I'm going on 3 months and $700 and I still have the original problem!!! Any ideas?
Have the ECM checked.
