WW says:

When you are trying to start, is there any smoke coming out of the exhaust at all (small puffs as the engine tries to fire)? If not, if might require bleeding the fuel system to remove air. Another possiblilty is water in the injector lines (might be worth checking the fuel filter). Water (well, ice crystals) in the lines can block the fine injectors and pump- draining the pipework, warming it (by hand, if needs be) then repriming.
Also, compression might need to be checked, but it is unlikely that there would be a sudden loss of compression, if no previous problems.
As suggested by Mike, might be worth checking the heater plugs, though you would expect some form of action, even if the engine was cold and the heater plugs were not functioning (it might be possible that the circuit breaker on the engine block (or fuse) might have tripped.
Let us know how it goes!

If the fuel has gone creamy that would cause problems,you would have to drain the whole system and use new fuel.Otherwise check heater plugs,fuel filters,fuel pump,or injectors.
