Does it turn over
Does it have EP on the gear indicator on the dash and the red light beneath the gear stick no longer illuminated
If it does then mine was the fuse under the bonnet
After a mechanic said it was ecu,ecm,fuel pump,fip, blah blah 235 mile recovery
It was a fuse
No really

When you tried to turn her over did the oil warning light illuminate - if not the ECU has probably taken a bath - the diesel ECU's are unsealed and prone to water ingress - was there a tide mark in the plenum chamber (where the ECU is fixed).

For future reference i would use the services of Big Russ a trader on here who lives off the M62 at Liversedge - he is a wizard on ECU's/keys/immobilisers and has a big stock of diesel ECU's as well as a T4 operator (MG Rover diagnostic system) - he is also better value than the ECU repair outfits.

Once you are sorted i would get the Plenum spyhole Modification to avoid the ECU getting a bath - search the site for the how to - see below a useful link.

If the ECU is OK -on a diesel i would also consider failing fuel injectors - so try a leak back test - if an injector is faulty there are traders on here will provide refurbed ones at lesser cost than a main supplier.

Other thing to consider is some diesels have an under bonnet 2 nd fuel pump - these can fail leading to non starts and stalls - a good tap with a screw driver and if she starts up thats your problem -also tends to strike if your tank is low on fuel.

Also worth a shout - could your inertia fuel collision switch have been triggered - i would have though that would throw a warning light - if it has tripped it will stop any fuelling to the car (to prevent a fire in case of an accident) - I think on the diesel its under the centre console.

So a few possibles - but if you can get a T4 on her that best - I think the old MG Rover dealer at Sproatley (Maples) still have the MGR T4 diagnostic - but not sure if the technicians are up to speed on it like Big Russ.

One other thing - more common on the 1.8 's is a corroded spade connector from the starter motor to the battery - pull it out - if it looks corroded clean up with white spirit/remove corrosion - its a known cause of non starts. If it is this a good clean and she should start OK.
