There is a sencer on filter when did u last drain filter this sencer has two probes in side filter when there is water present it makes a connection and stops engine starting so water isn't injected to engine and running ur in ejectors on bottom of filters there shud b a large plastic knurled nut on the bottom filter to turn and drain out water it will b tight turn anticlockwise couple times until fuel runs out personally I would recommend changing filters because they do get clogged un less u have recently done so
