Lilacs may take several years to settle in and bloom, so your plant is not all that unusual. Lilacs do prefer full sun all day or for at least six hours including noon, and a lack of sun can reduce blooming. Another common reason for lack of bloom is improper pruning. Lilac should only be pruned in the spring right after it blooms. The reason for this is that it blooms on old wood grown during the previous year. You might try giving your lilac some compost or a complete fertilizer such as a granular 5-10-5 in the early spring as directed on the label, but apart from that you may just have to be patient a year or so longer. It's worth it, though!
