Hello

its very likely that you have gotten water into the back of one of the engine sensors

so I'd remove each connector in turn and use some compressed air ,( or a foot pump) to blast air into each and remove any trace of water - using some switch or contact cleaner will also help clean things up

if this doesn't help then I'd start by checking for a lack of fuel and could be a lack of fuel pressure from the electrical pump at the tank.

1st thing to try is to remove the fuel filler cap and then flick the ignition on whilst listening for the brief ‘buzz’ of the pump

If the connections to the pump are corroded or damaged then the pump could stop at any time or could not be running at full speed. Check that its relay switches in and out and the relay contacts are clean and bright – replace the relay if in any doubt and do the same for the fuse,

Ideally measure the pressure at the injector rail (should usually be around 3Bar / 45psi +) and if this is low check the pump as described and also consider changing the fuel filter as if this partially blocked this too will reduce pressure.
