360 360 dead after washing

Being a nice sunny day in Kentucky yesterday, I decided to get the 360 F1 out for a wash, started up as usual and backed her out for a bath. After wash, nothing, turn the key and nothing. Lights work, push key fob and get double beep, red light off, turn key with foot on brake and absolutely nothing. Ideas greatly appreciated as usual. Ernie

Here is what happens at start:

In an F1 model with electro-hydraulic gear shift, where the crank command starts from the ignition switch, goes through a charge cut-out relay and through the dedicated crank relay, and then makes its way to the Transmission Control Unit. Only when the TCU recognises it’s safe to start will it then emit its own crank signal (negative switched) to the crank relay; so there’s plenty to consider.​

My guess would be either starter solenoid stuck or the TCU is not letting crank signal through.

What could washing the car have caused this? How can I troubleshoot this, thnxs.

Push it back into the garage, wait 24 hours and try again. You probably got water into something that didn't like it.

 

Did you wash engine bay ??

 

Let it dry out overnight and try again. Easy to get water in the engine bay with the louvers, you may never know what all got wet...usually the culprits are the ignition coils but you said it's not turning at all...

 

Take a leaf blower and blow the engine bay dry. You might of got some electricals wet?

 

That will work but when it happened to me I used a small wet/dry Vac from HD that sucks as well as pushes out air. The air flow is more directed and easily reached the smaller areas of the engine bay. YLMD
