2007 toy tacoma battery down, disconnected, reconnected, crank but no start

Help! I disconnected my bad battery in the evening and reconnected in the morning to save juice, jumpstarted and used all day. Disconnected next evening and reconnected this morning and tried to jumpstart and it cranked but did'nt start. Cleaned posts, checked fuses. Confused?

 

Check all grounds.

 

You went from one problem, to two problems.

Few questions.

Does your truck have an Alarm System?
Does the tach move when cranking?
With key On, NOT CRANKING. Does the check Engine light come on?

What's the plan once you find out why it wont start?
Are you going to fix the 1st problem? The battery drain over night?

 

What other people said. Why don't you replace the bad battery instead of jumping it? Probraly engine turning too slow, to start.
