Grass on the NC coast

Question

I bought a house with a yard full of weeds. For 4 years we have put pre-emergence out, then 10-10-10, then seed or sod. The grass grows green, dies out and nothing comes back up the following year except the weeds. Sandy soil, about a mile from the ocean, even tomatoes will not grow. We run sprinklers 3 days a week as recommended.
Any suggestions on what type of grass to grow?
I am tired of paying companies for seed and sod, and getting nothing to show for it.
Thanks, Greg

The sand doesn't retain water or nutrients so it's very difficult to sustain plants. In the article below, it recommends putting down at least 6 inches of topsoil before planting grass. Use seed mixes that are mostly hard fescue.
