My neighbors jaguar has failed to start, strange thing is it turns over like there is no compression?? Its a 1998 4.0 V8, can anyone give me some ideas on what could be wrong and how I can get it going? done 68k with FSH and he has never had a problem with it before.
tried cranking as recommended but no joy so guess its plugs out next, what is the significance of squirting oil down the plug holes? Is it something to do with compression, and turning over like a v12 - a constant whir?
