2003 Toyota Tacoma Engine Won't Start After Washing

5 minutes after washing the engine, my 2003 Toyota Tacoma stopped running & gave a code P0351. What can we do?

Steve Says,

This is a fairly common problem that happens when water gets in electrical connectors. The code that is set if for "ignition coil A primary/secondary circuit malfunction". This means that the most likely cause of your problem is water that has gotten into the connector for one of your ignition coils or the wiring to it.

There are a couple of things you can do. If you have time you can let it sit for a while and see if the water will evaporate away. If you need it going right away you can disconnect the connectors for the ignition coils and dry them using a towel or preferably compressed air.

Be sure to check all of the connectors that you can see under your hood to be sure they are not loose. Also, you should check all of your fuses just to be sure that none of them blew.

I hope this helps. Good luck!
