I just cleaned the battery cables on my LS400, and now it won't start. Gauges come on, but no sound at all. I pulled the positive cable off first, and think that may have disabled the car somehow. I tried jump starting with no luck, so I know its not the battery or the connection. Any ideas?

 

Not sure, but I know you are always supposed to remove the negative cable first. Did you check your fuses?

 

if it started before, and now it doesnt, that means you didnt clean them properly. Go to Autozone, or discount auto parts, and ask them for a contacts cleaner. Should be a red can... that will clean the suckers right up.

 

you can use warm water and baking soda to clean your terminals too.
