A remote starter was installed by an unqualified person (business) and my Buick quit running one day as I was driving down the road. It would only start with the remote starter, not the key. The following has been done to my vehicle:
1. Remote starter removed - personal mechanic with instruction
2. All wiring traced and repaired where there were nicks or loose connectors from the remote start - personal mechanic
3. Cold Start relay was installed at GM garage
4. New Passkey system installed and reprogrammed - GM garage

Car still has the same problem -- it won't start immediately in the morning after the car has sat all night. I put the key in and turn the ignition, it doesn't even make a noise. Then, I remove the key and push lock, then unlock on the remote entry and it will either start or I will hear the fuel pump. Then, if I keep trying using the lock/unlock on the remote entry, it generally starts after about 1-3 trys. It runs beautifully all day and evening even after leaving it sit for hours at a time. It's a great car; gets good gas mileage, rides great, etc. but this problem seems to be neverendings

Does anyone have any idea?. Has anyone even heard of this problem?
