I've finally managed to find the time to get the engine back in, although it wont start!

Ignition, lights etc work fine, but when you turn the key to start something clicks under the bonnet and I loose power to everything. Although it returns after about 20 seconds or so.

Now, is there some sort of safety trip out? I'm thinking somethings come disloged on the starter and is earthing out? Or could it just be a poor earth from the engine to the body?

Just wondered if anyone might have an idea before I remove the inlet again to have a look?

Strange!
