hello,

I cant figure out why the battery wont stay charged new battery terminals cleaned new alternator and fuses are all good.
check engine light is on pcm and fuel system are what come up when you check would this be the cause of the problem or could it be something else?

Please help.
Thanks!

I didn't find the right solution from the Internet.
