If you don't have any leaks it is probably the check valve in the fuel pump if you just cycle the key three times by turning key on and wait 7 seconds and turn off and wait 10 seconds each cycle it will start easier if that works and it starts fine the problem is the check valve in the fuel pump

The fuel pump might be working but it is not priming. When you turn on the vehicle, the pump sends fuel under pressure to the injectors, to "prime" or have fuel present to be able to start engine. Without it there will no fuel available to start it. You are manually priming the engine, and the fuel pump is taking over from there. Check connections to fuel pump and replace if necessary. It is not an inexpensive repair
