Omega General Help / Omega 2.2 Starting issues
« on: 08 January 2025, 12:29:25 »
Hello, I have a standard Opel Omega 2.2 Saloon with Z22XE, 4-speed automatic
My main issue is that the car wont crank. Issue appeared few years ago in wintertime when temperatures below -10C. Battery has power but when turning the key, nothing happens, car wont crank. Issue disappeared briefly for a year after a new battery swap but issue has come back. Battery is ok and charging it doesn't make a difference. No indications that starter would have failed. Maybe grounding issue?
Does anyone have electric diagrams for this enginetype? Ideas how the ignition switch is wired? Any relays to watch out for?
