Once in a while I start the car but the car does does not on.There is no action even when I try again. There is no sound, no click or any indication that there is any contact as if the key is not recognized. So when this happens I pull out the key and try few things like locking the doors and opening them, or insert the key into the switch few times until the car starts. I plugged in few times the engine tester to see if there is any problems and I got nothing wrong. I hope that someone has an answer for this problem of M45, 2003.
