Most citrus, especially those started from seed can take anywhere for 3 to up to 6 years before you see the first flower. If this grapefruit is from seed, then it is not going to be a grapefruit. The way the pollination works to get these makes the seed revert back to the parent tree.
If your grapefruit was purchased as a mature grafted plant, then it could be something as simple as a lack of fertilizer.
You should fertilize these once a year with a citrus fertilizer.
