wont start

I have a 1997 Disco, went through some deep water a couple of weeks ago everything ok, stopped and started for rest off the day ok , parked up in workshop and left for the week, decided on Saturday to check axles for water and tried to start nothing all lights come on turn key everything goes out, but no lights from factory alarm immobiliser and no power to starter.

Put boost leads on still nothing checked battery plenty of live, disconnected battery and re connect and it turns over but wont fire and no lights for standard alarm.

Checked lift pump fuel to injector pump, checked stop and power to stop.
still wont fire.

Checked cam belt and all ok just to be on safe side.

Three wires from stop got 13 volts to two and one pulses.

Checked green alarm box in dash board all seems ok and dry.

Has anybody come across this before as im running out ideas

thanks

how do yu know everything is OK?

green box looks ok no damaged solder all points look ok and is dry

cam belt is turning pump when cranking and is tight

have yu checked tapped gaps?

So you are saying that you went through deep water and now its not injecting diesel?

what makes you think these are related?

maybe connected

All I know it was running fine when I turned it off and no wont start at all even with stop disconnected.

But the immobiliser has stopped working, no light on and key fob not doing anything at all.

it is a edc model.

lift pump is working ok got fuel to the pump but nothing to the injectors

thanks
