New battery cleaned the terminals. started yesterday & 2 day. but won't start know

i would look at starter

There can be a few reasons,,,
1. Bad battery.. Have the COLD CRANKING AMPS checked
2. Bad battery connections.. clean and tighten both battery terminal cannections
3. Bad/going bad solenoid
4. Bad/going bad starter

Could be anything in the truck. The best way to narrow this type of problem down is to due a parasitic draw test. This is done by disconnecting the ground from the battery. Then connect an amp probe inline between the battery and terminal. Watch the amperage on the meter, it should drop to 5 ma or less after 10 min. This is sleep mode. If this happens you either don't have a draw (drain) or you have a draw that is that can't be duplicated at this time. If your amp draw is still over 5 ma after ten min. Something is staying on. To find out what that might be. Without opening any doors or actuating any switches, start removing and replacing fuses while watching amp draw on the meter when you see the amp draw drop you have found the circuit that is draining the battery. Hope this helps.

Try cleaning battery terminals

I am not familiar with hybrids, but i think when you start, it's starting with the battery, so I think you have a bad connection, check and clean the battery terminals.

check your battery,or not clean battery terminals,or starter motor solenoid.

Make sure battery terminals are clean & tight.Also make sure polarity is correct & battery is fully charged.Thats a good start

If you indeed installed the positive battery cable last and the neg first you blew the computer possible, you will need a complete diagnosis.

Clean your battery terminals. Make sure you take them off the battery and clean the battery poles too.

You need to try and jump start the vehicle and see if it will start. It sounds like your battery is bad to me. The interior lights are not a good indication of battery conditon, because a starter can pull somewhere between 30-50 amps draw from the battery, where the interior lights may draw 2-3 amps.
Also check your battery terminals for condition. Baking soda and water solution will clean off corrosion, followed by a terminal cleaner from an auto parts store. I would start there. Let me know if that helps.
