I'd start with the fuel filter/primer as Norsk stated, ensure the filter is still on firmly and that the seal isn't leaking (may have vibrated loose from hanging free for a few days), check the hose clamps on fuel filter are snug check hoses to and from filter for wet spots indicating a hole/leak.
pump until firm then try starting. If no go then try again but glow twice before starting (if this works it indicates the glow plugs are not working correctly and it may be time to replace them, also check the metal rail that connects the glow plugs is bolted onto the glows firmly.
Does it puff out any smoke as you crank it? this may indicate unburnt fuel.
