Right I'm having problems with my earth lead from body to engine it's intermittently not starting the earth lead connects from the body to a bolt on the engine but the bolt it connects to looks like another bolt that screws into the engine this has some play in it and if it don't start I just push that bolt and it fires up I've tried to tighten it but it won't go anymore does anyone know what it's called or if there is another point I can connect the earth too it's getting a little frustrating I've replaced it with 2 new earth cables and it still happens any help would be appreciated

Undo the bolt and put a couple of washers on the bolt and tighten up.

Thanks I'll give that a try
