Technical Ducato X250 immobiliser light on and won't start

[321tom]

Ive noticed a slight tear towards the end of the earth strap were it bolts down. Im debating weather to buy a new strap from halfords or put some jump leads on it.

Ile buy some contact wd40 contact cleaner and check the plugs around the Ecu.

In the past i had a problem with a fuse box that moisture had got in. I had to buy a new fuse box and put a new earth wire in the loom as that had melted. I havnt got any burning smell this time so dont think it will be the fuse box.

Would you have a new ignition switch fitted before it gos to the auto electricians on a truck.
The local key chaps think i should try the ignition switch first.

Ive read that a faulty ignition switch could,

Still crank but not start.
Put the padlock sign on.
Ecu not reading.
And engine stall.

All of which are the same symptoms.

I had another one of these as im in the motor trade and another common problem is the fuse box gets moisture in it which causes the earth wire to burn out, if you catch it early you wont have your van electrics set on fire.

I’ve only had mine since November last year -
I cut my mechanical teeth on my parents Lancia’s, Fiats and Alfas, so having already chased numerous electric gremlins on those I preemptively had the Ducato’s under bonnet fuse box out and cleaned every single connection, clean all the ecu connections, replaced and added earths then sealed the scuttle so fingers crossed - at least they keep us on our toes….
