OH NO fault codes !!

[boomtown]

Took care out a minute ago and all of a sudden it started spluttering and misfiring !!
fault codes as follows
16684
16686
16687
16688
16690
i know these are all cylinder misfires
17658=fuel level to low !!
i noticed a smell of petrol when i started it, im hoping a blocked/clogged fuel filter ??, car is running ok now
any ideas ??
cheers
