If they are cheap than most likely you got water into the electrical piece (cant remember the name of it currently) and thats the issue.

Doh.... that's why it's a good idea to disconnect the battery before spraying the engine bay. Check fuses/relays.

Next time put a plastic bag over sensitive electrical components. Washing your engine bay without proper precautions leads to more problems than solutions.

It could be worst, it could have been his starter or alternator. I never ever spray down those 2 or the CAS/distributor area.

put a condom over it then electric taped it,doing this should make it water "resistant"c
