I have a 2005 Acura TL no start issue. I am trying to get my car running again. After reading these repair forums. I was thinking of my immobilizer and ECU needed to be reprogrammed again to dealer but didnt want to spend anymore than I should. My green key light on dash blinks, no sound of fuel pump kicking in. Still buzzing sound when turning key to try to start car. So does the key cylinders tumblers and wafers has to be in good connectivity in order for fuel pump to be turned on as well? I replaced relays already, As of now I was planning to do away with these immobilizer crap and trying to find which IC chip to remove in the ECM, so no need for these immobilizer handshakes to be made, but only a fitting key to just start my car. Any help and suggestion anybody?
