u/Electrical-Focus-968

Hi everyone, I have a 2005 Peugeot 206 and yesterday night I started having a strange electrical problem.

The car cranks but won’t start. The parking lights / side lights (the small position lights) turn on by themselves when I turn the key to the first position.

I also can’t turn on the other lights (main beams/high beams) or the turn signals. The dashboard shows “ECO MODE” as well.

The windows still work and the engine does crank normally, but it just won’t start.

This all started after I was checking/replacing a small LED light in the trunk area.

Could this be a blown fuse, relay, BSI issue, or some kind of electrical short? Any help would be appreciated.
