i just got the car, so i have no idea what happened to it. also for sum reason, i found that the harness to the fan on the radiator was unplugged, and whoever had the car before ran a wire to it that would turn it on with the ignition. and if i re-plug the harness the ran just runs all the time. the gauge cluster is plugged in but doesnt work.... well it will flash wit the hazards but that's it.

could an ecu going bad do any of this ?
