Short?
 

Hello i have an 02 ssei and it wont start. Some days it will and others wont. or if i leave a door open when its not started it dies i had the battery checked and it came back fine. Any help would be greatly appreciated.

Check the main ground by the battery. It's been found that it's usually bolted over a painted hole and makes a poor ground.

Another area I would check is where the grounds bolt to the transmission down on the front of the bell housing.

thanks i will check that out

thanks i will check
