Computer Problems

[RangerAg09]

About a week ago, my truck started to idle erratically and it was running really rich. We checked the fuel pump, regulator, etc. and everything was fine. So I replaced the computer and started her up and she ran just fine for about half an hour while I drove around town. When I got back home and turned her off though, she wouldn't start again. All I get when I turn the key is a click and silence. Any thoughts to what it might be?

A dead battery, battery cable, or charging system.

And your computer may very well have been fine.
