    Hyundai 480 will not crank. Batteries good. When turn key to on travel alarm beeps. No response from engine. Fuses have power. Swapped relays and same issue. Any ideas?

    I just re read your original post. Your travel alarm comes on with ignition? If so, could have failed sensor. That in turn could be tricking the computer into thinking the safety is engaged and travel is requested. Just a thought. I have nothing to base this on other than your description.
