2004 Hyundai Elantra Shuts off on Freeway
Manual transmission, no warning, just loses all power and turns off. Will take a while to restart. No fluids noticed on ground and no odors or warnings that this might happen. New battery was installed just a couple months prior because the stereo would just cut out and stop, then the car would not start sometimes. Do you think it could be an alternator or cellenoid problem? I have also seen some advice suggesting fuel pump or filter. There is no rough start or running suggesting a clog....it just shuts off and loses all power. Very dangerous for my son who drives the car.
start with the fuel filter and air filter, then move on to inspecting the battery do a charging test,test the alternator, h/t leads, plugs, it would also help to run some injector cleaner through it, check the operation of the coil pack, undo the coil pack connection clean it and reconnect it. i hope this helps.
