Over the last few weeks I have been sorting the bodywork out on my mpi. I have finished this now, the car started first time this morning. When sorting the bodywork I have a bit of a welding mishap whereby a section of the rear loom behind the fuel tank caught fire. This has given me a couple of problems, the indicators wouldn’t work, and the rear fog lamp came on with the brake lights. I have now sorted this and was sure that the section of rear loom was suitably repaired, though it was difficult to see due to the location of the damage. I have tightened the battery terminals.
So after sorting these small electrical problems this morning I tried to start the car again. However the key fob does not turn off the led alarm/immobilizer led on the dash – the light flashes as normal, after 2 clicks on the ignition the light turns solid, ie no longer flashing, as normal, but the fob will not turn the led off. If you turn the key as if to turn the engine over nothing happens. I checked all of the fuses. Has anyone else had this problem or does anyone have any ideas as to what this might be? I think its unlikely to be related to the rear loom damage, is anyone able to confirm this?
My thoughts would be to check the starter wiring, however the dash led does not turn off, so im sure its an immobilizer/fob problem. The fob always turns the immobilizer/alarm off first time, so I find it hard to belive that the fob battery would just go flat? I believe it to be an electrical gremlin in the car wiring/ecu/imob.
If anyone can suggest any causes or anything else that I need to check I would be greatly appreciated.
Thanks, dan

I do not know if this will be any use but you could try resynchronising the fob by pressing the unlock button at least four times.

You can open up the key fob and look at the the three solders on the batteryholder. You might have hairlinefractures on them. Orangeboy gave me this tip when I had immobilizerproblems, and it turned out both my keyfobs had this problem so I think they must be quite fragile. Otherwise I feel this post might have som value in the tread on welding on an SPi/MPi.
