Occasionally my 2004 Isuzu Ascender won't start. Full power, batteries fine. 13 or 14 volts on the battery meter. All the dashboard lights light. Car battery is new. I have also had a dealer replace the ignition switch. There is no computer error message being sent to diagnose it. It just turns and nothing. Eventually after a few minutes it starts on it's own. It acts like a short but nothing is done and then it just works. No real pattern to it. Nothing I can do to make it work.
