Does it run and stall, or not run at all? It may be as simple as the starter not turning fast enough, or fuel pressure. Try doing a fuel pressure test on the system. Listen for the fuel pump to whirr for about 15 seconds when you turn the key to start as it pressurizes the system. If you're not hearing this, it's fuel pump or relay. You may also have other problems, drop me an email once you've done those things.
