I have a 98 C5. I was having some intermittent ignition issues and diagnosed it to the switch. I replaced the switch and many of my issues as well as ignition were resolved. I enjoyed 3- 4 days with absolutely no issues. My problem now is that the car will not start in the morning. Turn the key and everything cycles fine on the dash but turning to crank nothing happens. No clicking or anything. Oddly, when I come home in the early evening and try and figure out whats happening it starts like there is nothing wrong. I tried off/on multiple times and it works just fine. It has done this last two days. No morning start but fine evening. Any ideas?
