It sounds to me like it lost it's prime. It could have an air leak, or it needs bleeding again. What I would do is crack two of the fuel lines and crank it until it squirts fuel out of the injectors. I will tell you, if it starts squirting fuel out it will probably start, and run really bad, until you close the opened injectors. That may get it started but if you have a fuel problem it will happen again the next time you shut it down and try to start it again. If it starts, you need to make sure the system is sound.
Good Luck

It's a 275 HP ISB engine in it.

It has a 12V fuel pump.
Turn the key to on and wait a while as the pump will run.
Turn key off and then back on to repeat the pump running.
Then try starting.
