Very basic question. Just started a new project. Track one ... scratch guitar track (following click). Track two ... vocal. Vocal click track is out of sync with track one. How to correct?  

Hey, there.  I am not clear.  You have a track with a click, a track with a guitar, and a track with a vocal?
Or do you have separate click tracks for some reason?  Most people just use one click track for everybody, but maybe I just don't understand.  If you can explain, I will try to help.

Prolly a latency issue.
 
I always review position of all clips. If automatic delay compensation has not done it duty, I just zoom in and move the track to what sounds correct.
 
To move audio clips to the left it is often necessary to trim the beginning of the clips.
 
 
 

I'm at the beginning of a project - open Sonar - create new project. First thing is I insert an audio track and then record guitar following the click (meter) which I adjusted from 120 to 94 tempo. Next I insert the second track to add a vocal. Start the click to follow first track (guitar) and the click (meter) is now not lined up with the original first track. The click is the same meter but ahead of the first track by a small margin. I have not added any effects at this time. What is the solution to get the click on track two to be in sync with track one?

Just to be clear: By "click" you mean SONARs metronome, or something else? A click track and metronome are not the same thing. Or are you using some kind of a click VST?
You say you "start the click" before recording the vocal track, and starting the metronome without actually starting playback or recording is something I thought can't be done. But I may be wrong, of course.
As suggested above, it might be a latency issue. Maybe the original guitar track actually records off time compared to click due to latency, or the vocal. Check that the guitar tracks start position is spot on.
Is this a new problem? Did you change any settings before it started?
 
What is your interface and what driver are you using? Such problems are very typical to motherboard soundchips and MME drivers.

Another obvious question.  What version of Sonar is this?

Are you monitoring directly, or through Sonar?

You may have the metronome following the nowtime ruler not realizing it's not aligned exactly at the start of the project. If the now time is set to 1.00 or whatever make sure that the guitar and vocal recordings are also at that same now time. I always click off 4  1/4 beats and start my recording on 2 so it gives me some time to get ready and it's always spot on no matter what the clock is. It could be latency but I haven't seen it yet in Sonar 3 using the internal metronome.

Thanks to everyone helping out. I just recorded a couple measures following along with the metronome. As I play it back and listen along with the metronome, the part I just recorded is not in sync with the metronome. The recorded part is slightly behind the metronome when listening to playback. I've recorded before and this wasn't a problem. Just been absent for a bit, getting back into it and stumped here.
