Hello, my name is***** would start by adding fuel to tank, if that doesn't help then do a fuel pressure test. Fuel pressure should be around 50 psi key on engine off. If fuel pressure is low check power/ground at pump. The green wire should have power while trying to start and black/white wire should have ground. If power/ground is good but no pressure replace the pump. Let me know how it goes or if you have more questions. Thanks.
