If the engine has, up til now, started easily then a sudden loss of compression is kind of unlikely. If it's been difficult and slow to start, esp when cold, then it may be that you've been "on the edge" of adequate compression for some time, and it's finally gotten to the point of not running.
Your symptoms do sound like a fuel problem initially, and aside from a major compression problem, fuel delivery will continue to be the most likely candidate. Fortunately injection pump failures are quite rare too, so it may not be a costly fix in the end.
