Fuse??????

2002 Frontier, trying to install extra back up lights I blew a fuse, now I have no back up lights and the truck won’t crank, like there’s no power going to the battery, anyone know what fuse I should be looking for?
Thanks
Joey

I'm guessing you left the battery connected while you were screwing with the new backup lights wiring. You have a short. You need to back track your work.

On the 2002 Nissan Frontier, the backup lights and the starter relay often share the same power source through the 10A fuse at location #13 in the interior fuse box (behind the coin tray/dashboard). If that fuse blows, the truck won't crank because the "Inhibitor Relay" (which tells the truck it's in Park or Neutral) loses power.

Check that #13 fuse first. If that’s fine, head to the engine compartment and check the 80A or 100A main battery fuse (fusible link) near the positive battery terminal, if you shorted a major wire while installing the lights, you might have popped the main link, which kills power to the entire ignition system.
