Hi I've got a 2003 scudo that won't start.The engine turns over but won't fire.When ignition is switched on the warning lights for glow plugs engine managment and abs do not appear. Have tried all fuses, glow plug relay, inertion switch, checked the earths, visually scanned the wiring can't find any breaks or loose connections is it the ecu or something else.Was running like a clock till 3 weeks ago had temps of -12 then this problem any ideas.:bang::bang::bang::bang:
