Ok, ive seen post kinda similar to my problem, but not similar. 2000 odyssey 200k. went to leave the store and turn the key to let it prime. turned the car over and it started, sputtered and died. waited a minute and turned the key to prime and i have no power to the cluster. everything else in the car has power but not the cluster. but when i go to try and start it again and its turning over i get power to the cluster, it starts, sputters and dies(see video below). Things i have done,
cleaned battery/terminals, pulled main relay and check points(see picture below), pulled spark plugs and scratched/cleaned them up. the reason i have not just replaced them is because i wanted to see if there was any diff with starting the car if they were cleaned up, no diff. checked all fuses.last thing, i took plastics off steering column and tapped around the ignition while trying position 1 and 2. nothing happened/changed. i did find a what looks like a bad solder spot(see pic below) but i do not know what this wire is for.
i do not know how to do videos so i hope this link to youtube is ok.
i appreciate any help in advance. this is our only car.

main relay

back of ignition did not see a spark
