Hi I started my Tacoma this morning and when I turned the ignition it had one crank and everything shut down completely. I thought it was the battery so I changed it to a new one. Tried to start it again and nothing. The connections to the battery is clean and tact. Changed the starter relay to a new one. All fuses are okay. There is no power, dash light is not working, horn doesn't work and exterior lights don't. I'm not sure if it's the whole ignition lock and cylinder I will have to change. Help would be much appreciated! Thank you.
