i did everything u said, so still nothing

sounds like the 75a fuse it happens if you ground the alternator wrong say you put the ground on there with out the plastic insulator it will blow the fuse it has a clear plastic top in the pass side fuse box by the battery

that was the first thing i check and it was good, either way i got a new one, plus i get power to everything else, headlights and the inside lights powers, but windows wont go down, rear brake lights dont turn on, and i dont hear the fuel pump running, stereo not on but it has power...hahhhhhhhh!!!

ps i change the ecu
