Putting primer on an old dry wall - Which primer to use?
I have a dry wall in the kitchen that has some stains on it. I would just like to put a new coat of white primer on that dry wall so it doesn't look stained.
My questions are:
1. Should I sand the old primer off from the dry wall first? Or simply start putting new coat of primer on the dry wall?
2. What kind of primer should I use?

Just the usual cooking. They aren't grease stains though. If I take a wet cloth and rub really hard I can get few of them out but some still are hard to remove. so I'd like to put a new coat of white primer on it.
Should I sand the wall first and then apply primer?

If feasible it is always best to prime/paint substrates that are clean and a light sanding always helps to promote good adhesion.
Not knowing the exact cause of the stains I'd recommend using an oil base primer. May stains have the tendency to bleed thru latex primers. Primer should never be left as the finish coat. A latex enamel would probably be your best choice for a top coat.

I think you intend to only prime the wall, at least that's the way I read your question.
Don't do that - a primer will allow the stains to show through so you would continue to see them anyway and primer is not intended to be a top coat and as a result does not wear well.
Mark gave you good advice on how to tackle this.
