Help! Truck won't start!

Tried searching but I'm kind of in a rush. Put a system in my 2000 Tacoma SR5. Took the positive terminal off the battery so I could put the power wire on. Hooked everything back up, and everything works.....except the truck won't crank. All my dash lights stay on when the key is turned and nothing happens. Tried jumping it off, still won't work. I turn the key, and nothing happens. No clicks. No pops. NOTHING.

Do I have to reset something? I took both terminals off for about 5 mins, reconnected, and still nothing.

All feedback welcome, this is kind of urgent.

 

Maybe blown ignition fuse.

 

ALWAYS remove the ground cable first before you add anything, even to the positive cable. As mentioned above, you most likely have blown a fuse. Check the underhood fuse box fuses.

 

Nevermind......delete thread......I'm an idiot.
