Dear customer, I understand the first thing that comes to my mind as i am not with the vehicle is that it could have burned or disconnected the fuse of the immobilizer system, what happens is that when this type of fuse is touched or damaged the computer of the the vehicle may think it is being stolen by a bypass which causes it to activate the immobilizer system for safety.

First, i want to explain how your immobilizer system work

The electronic immobilizer protects your vehicle by means of an electronic code integrated in the key. This is composed of an invariable personal code and a second code that the immobilizer modifies each time the engine is started.

When starting the vehicle, the immobilizer checks the personal code and the variable. If both codes are correct, the immobilizer sends a new coded signal to the engine control to unlock the engine. Without this signal, the engine can not be started, even by a short circuit.

Primero permíteme indicarte como funciona el sistema inmovilizador.

El inmovilizador electrónico protege tu vehículo mediante un código electrónico integrado en la llave (no necesariamente por medio del chip). Este está compuesto por un código personal invariable y un segundo código que el inmovilizador modifica cada vez que se arranca el motor.

In your case dear customer, we can have a problem with the coding between the immobilizer module and the coding of the key or barrel causing the vehicle does not pass the start by having the immobilizer activated.

Solve this is not very complicated dear customer, Only requires a key programmer to re-code the immobilizer with the set of keys you present and with the cylinder/barrel system.

This equipment is not generally owned by mechanics, but it is owned by locksmith companies that are in charge of opening vehicles, cutting car keys, and programming keys and key fobs. This is the kind of company that you must contact to solve your inconvenience.

It does not mean that you can only have a problem in the immobilizer system. I will recommend you to check the fuses but not in the way they normally do but locate a tester and check from that equipment if there is continuity in each one of the ends/tips of the fuses, in this way we will know if they are ok. Many times, even though the fuses are good when reconnecting them we let then loose or the connector, are damage or loose as well, causing that there is no communication with the fuse and this causes this type of problems, the only way to determine if they are really working correctly the passage of current of the fuses is to determine it by means of an electric tester, I am also going to recommend that you locate the manual of your car and look if the manual have the fuses and relays diagram, if you do not have it, in the cover of the fuse boxes should be a sticker with the legend with the location of the fuses and what system they belong.
Locate the fuses related to the starter system, fuel pump, immobilizer. Many of them are relays and verify that these are in good condition and also that they have their correct connections.

Anyway dear customer, the check of the fuses is the first step but it is not a bad idea to perform a computerized diagnostics to know if simply when disconnecting fuses no error code was generated and it is causing this inconvenience, because determinating from my position is very complicated, but it can make you these recommendations to help you locate the root of the problem and sort it out.
have you understood me dear customer?

I have found out that it is an issue with the fuse board relating to the ignition. It looks like it got wet somehow. The fuse board is a Magneti Marelli 503440830200. There are none here in Ireland. Do you know where I could get one?
Expert:  sebastian manrique replied 9 months ago.

Dear customer, you can check for the fuse box in ebay, generally ninfoundnparts there, I you wish I also could try to help you nlocate the part in others sites as well.
