Turn ignition 2 times to start, runs with foot on gas, won't idle alone, car dies. Is this an idle control switch or sensor or fuel problem? Installed a starter a week ago. Turned off air conditioner(about a month ago)while running, and the a/c won't start. Replaced the blower, fuse is fine. Does the compressor have a relay switch?What else could it be? THANK YOU very much. I'm sorry I am broke and this vehicle is my son's with a sore wallet!
