Good evening Iliannys, what happened is that the anti-theft system activated. What you need to do is leave the key in the ignition so that only the dashboard lights come on, without starting the engine. The red "theft" light will be on or flashing. Leave it until the red "theft" light goes out (about 20 minutes). Then remove the key and wait a few seconds, and it should start. Does it not have an alarm installed? Because that could cause the computer to reprogram. When that happens, just leave the key in the ignition. The anti-theft system cuts the power to the injectors, not the ignition coil. Let me know if you have any questions. Regards
