I'm having starting trouble with my disco. I recently drowned it, hydro locked and all. Got it running and driving but every now and again the bloody thing won't start. Sometimes I can leave it for an hour or 2 and come back flick the key and it will fire away. But other timed when i turn the key all i get is a click similar to flat battery. I'm wondering if it has something to do with the alarm system as it is constantly going off( I disconnected the horn cause it was getting irritating) any ideas or pointers?
