Are you interested in finding a sport that would work for someone with your level of disability? You might be interested in the SELF ASSESSMENT WIZARD on Parasport a British Paralympics website.
It is very easy to use. You put in your disability (e.g. Spinal Cord Injury). Then give more information (for example Quadriplegic or paraplegic). The Wizard then suggests sports which you might want to consider.
Keep in mind, however that recomendations are limited to Paralympic sports and there are only 20+ of them. There are alot more disability sports around which are not listed there.
If you are looking for a sport which might work for you, it is a good place to start. Another possibility is to simply watch wheelchair sport videos and find one that looks good to you.
