PANIC. 1.6 HDi 16 engine keeps stalling after start

Please help--I'm stuck :-( 

Has anyone seen this? I don't even have the Haynes manual, because that's on the other side of town :-(

The fuel filter light stays on, and the engine starts willingly, then stalls about 2 seconds later, whether it's idling or making power (struggling to clear the junction).

There seems to be no water-in-fuel sensor--I think I remember it goes in the fuel filter. I opened the drain a week ago and NO water came out onto my catch tray, only clean fuel.

It rained quite hard overnight--would the engine start then stall if the ECU got a false signal from wet wiring?

Also, where is the fuel pump driven from? A relay somewhere? I'm guessing yhebrelay should stay on from when the engine is being started.

Roops :-(

Re: PANIC. 1.6 HDi 16 engine keeps stalling after start

raining

problems afterwards

Does sound like relays or maybe even ECU got wrong signals, as everything is electronically controlled, finding fuel pump feed hardly is going to be of much help, but spraying either wd40 or silicone on the fuses/relay box might help to disperse the water and even to warm up engine enough to get it going again.

I've 5008 (2.0 DHI) with similar problems, my own testing with ODB2 was useless, compared to what mechanics found, like relay on the battery being dead, that explained occasional need to turn the key several times and sometimes needing to wait for 5 minutes, to try to start.
Why am I telling you this?:

I believe, it's electric and even electronic issues you are having now, try decent, knowledgeable and experienced mechanic to diagnose the fault and suggest you a cure, but I doubt it'll be solved on the spot, as a breakdown repair

Whilst of no real answers, but hope it is of some use
(Again, not a mechanic, only a keen observer opinion)

Update: After it hadn't rained all day, I tried again--engine started as normal, without an stalling while I drove it for an hour to recharge the battery and test.

Left it in only moderate rain all day and it starts and runs fine. Weird.

This could take time!

So I'm reasonably sure it's water somewhere. I just have to find out where :-)

Have a look at the  engine fusebox, under the bonnet drivers side, in my van. Unfortunately they decided to integrate as much of the functionality as possible into a single unit - so little chance of replacing a single faulty part. But worth having a look at the connectors and fuses for corrosion. This is a pic of mine.
