You are a little short of info here. Does it have a throttle body set up, port injectors, it all makes a difference. will it run if you give it a sniff of starting fluid? If so, check for power at the injectors or throttle body with key on, and while cranking the engine.Could also be a bad fuel pressure regulator. Check the fuel block for fuel, and pressure. Good luck.
