Help! TD5 oddness after water crossing
I did a short water crossing earlier (to get to Pebbly Beach camp ground in Yuragir National Park) it started off nice ad easy but for a few secods the water was over the bonnet.
After I parked my 03 Defender TD5 and set up camp I heard the fuel pump running for a few seconds.
About 5 minutes later the quiet was shattered by my horn sounding continuously. I managed to silence the horn by turning the ignition and firing up the engine.
However, the fuel pump keeps running of its own accord.
I've had a look at the ECU etc under the driver's seat and it all looks okay and dry in there.
What else should I be looking for? Will it rectify itself (ie dry out)?
This is my final night's camping in what has currently been a 5900km tour of Oodnadatta Track, Strzelecki Track, Coober Pedy, Corner Country and the Flinders Ranges. I don't want it to all end on a sour note since I am camped in a location only accessible during low tide! 
I'll be using my water bra on the way back over!
