1998 Honda Accord Radiator Upper Tank Crack-Replace or Repa

Thanks for your reply. Well, I got the radiator thermostat and hoses from Autozone, but after draining the fluid and removing the old radiator I noticed the new one doesn't have a drain valve! So I had to return it to the store which had to order another one. Anyway, I decided to temporarily glue the crack in the old radiator and reinstall it (I only changed the upper hose which was split on removal). After reconnecting everything (fan cables, coolant hoses and transmission lines, CTS connector and batttery negative) the car WON'T START. It cranked-but then kind of sputters before quitting; lights, blower motor and accessories work. I topped off the ATF and retried but it still won't start-less rough rocking/sputtering though. I notice that turning the key the "ON" position without starting there is hissing/low hum sound that last for about 2 seconds and the "check engine" and "maintenance required" lights quit at the same time as the hissing/low hum sound, leaving on, the two other lights (oil level + another one I don't remember). I notice all the lights usually stay on working car with the key in the "ON" position. Would appreciate your feedback on what might be wrong here.
