Mitsubishi

My car (mitsubishi endeavor 2004) did not start today. we checked, it is not a battery. when we are trying to start it, all lights in solon and dashbord start blinking, we also hear clicking sound near ignishion. car was working fine the night before. we have never had problems with it. whats wrong? thank you!

You have described an alarm system that shuts down the ignition and flashes the lights when activated.did you buy it used?i would be looking under the dash for a module and wires that have been installed after the car was built.
