Hello everyone, I have a 1997 Fiat Ducato 2.5TDI Capuchin motorhome. Can anyone tell me where the ECU is located?
 
As @Communicator says check under steering column shroud.
Note as has been mentioned parts may be past their "sell by date" so most reliable option may be direct power to the solenoid as the pump is a fairly simple set up.
Does your electrician know this model and age. It's a long way from modern ECU immobiliser systems.
If you just want to get it running many have gone the route suggested and at little cost, just a bit of labour with a Dremel etc.:)
Often the fault can be in the circuitry behind that shroud , so you may have to access it anyway.:)


Regarding your statement,

How do I remove this key security system? Do I have to touch the injection pump?
 
Sorry I was at daughters. Just got back.
If OP looks at their injector pump and it looks similar to this photo but with a cover over the area around the four injector pipes and also covers the solenoid, then what he has to do to bypass the immobiliser is carefully cut off the security shroud to get to the solenoid as it in this photo, he should find that a 12 volt supply directly to that solenoid directly above the four injector pipes will open the valve allowing the diesel into the pump so that it can be bled and started.
He will need to safely insulate the old wires apart from one 12 volt supply possibly via the ignition switch.
Note he will need to be careful not to damage anything else, as a new Bosch pump is very expensive !!!:(

Regarding the wires, do I cancel two and only connect the 12volt one?
You will need what ever gives you a 12 volt supply that comes on with the ignition switch and goes off when you turn engine off, the other wires will need to be safely disconnected.
All you need for the pump to work is the solenoid to open.:)
