Have a 2009 Mazda3, when I get in to the Anti-Theft and AT light comes on, no crank no start obviously. If I leave the key on the anti-theft light will go out but the AT light stays on. I've had it looked at several times by a friend of mine who is a reputable mechanic with the latest Snap-On scanner and all the tools to get it moving again and when I go to start it the next day or whenever it does it again. I have already checked all the relays and all the fuses actually switch them all out. Any ideas would be great.
