ok the guy I work for lives in florida. Im in hawaii so I cant help him out on this. He has a 94 4runner 6cl 2wd he sent it in for service. oil,brakes,steamed clean the engine bay.

First off the dealership broke his valve cover glued it back together it was leaking and they replaced with a new one. Now his alarm is not sounding when he turns it on. When his wife was driving it today it just stalled on the freeway. but started back up right after. I was thinking when they cleaned the engine bay water got some where it shouldnt.

The dealership says there are no codes and no water in the coil?

He did notice the fuse box was open under the dash??

he is the type of guy that has every service done when its due. 100% of the time.

I think its eletrical but dont know where to start
