i have a 2004 honda odyssey exl with 168k miles yesterday i went to unlock my van but it didnt work so i went n manually unlocked my driver door and realized my battery was dead. the piece thats in my brake pedal came out so my brake lights killed my battery so i put it back in and we jumped my van it was running and my husband drove it and everything. now its acting crazy went to crank it and now theres no power like the battery was dead again jumped it off ran n drove fine but as soon as u cut the van off instantly theres no power like it has a dead battery and i cant crank it. weve checked the battery cables made sure they were fine and still nothing. thinking it was the battery we took it back to walmart but they said its fine. we just changed out the ecu and ignition for another one from a previous issue we thought we had. idk whats going on this just started yesterday. we did just change the main relay last month cuz it went bad too. it was running and cranking fine til now. any one got some ideas we can try to get this thing going again? im losing my mind. also my dash lights will come one at frst but turn they key and theyre gone. walmart charged my battery today too testing it we put it in every light was on til i turned the key n all it did was click and die
