So like the title says i have a 91 accord lx (bone stock) that i just picked up and it ran great for the first week then the other day just said no when i tried to start it. when i roll the key over to start it it just clicks and all the power cuts out kinda like if the battery was dead but i just put a brand new battery in it so i know the battery isnt junk and the weird thing is that it will start if i jump start it. also one more lil weird thing to throw in here is that when i try to start it without jumpstarting it i roll the key over and like i said the power all cuts out but as soon as i roll the key back every single light on my dash comes on and my radio starts flashing. any thoughts?

 

Check/clean all your grounds. Second check your alternator, as its probably not keeping your battery charged. Otherwise bad starters have been known to cause weird electrical issues.

 

ive already replaced the starter and all grounds and the starter but those werent the problems. it turned out to be a short in the positive going to the alternator
