Hi folks I have a 2002 C5, am having a problem starting the car. Full power in car, no problem with radio, lights, electric windows etc....nothing going to engine. Fuel gauge reads no problem Problem started 2 weeks ago. Turned on alarm, then off again and car started no problem. Next day a delay of about 20 seconds before it started. Next day 30 seconds before engine started. This then increased to 5 mins and then 30 mins. Anyone have any ideas Thanks
