Need help changing fuel injector on 2001 Fiat Ducato 1.9TD.

Hey there so I need to replace a fuel injector on my van and I've removed air intake manifold etc in order to gain access to it. From what I'm reading the next step is to disconnect the fuel pump relay in order to lower pressure in fuel lines but the problem is I can't find it.

Does anyone know how to identify the fuel pump relay, or have a diagram of the fuse box on a 2001 1.9TD? Or does anyone know if there's another way of lowering pressure to fuel lines in order to safely remove the injector? Or can the fuel injector on a diesel be safely removed without lowering pressure anyway?

Any help would be greatly appreciated. Cheers

Welcome at FiatForum.

No need to take of the relay connection.
Just unbolt the fuellines, maybe some fuell will come out, but not much.
Remember to use compressed air to clean the injector surroundings, and use a lot of penetrating oil to loosen the injector clamp.
Also use carburetorspray to soften carbon build-up, specially if one, or more injectors (seals) were leaking...use it a lot, and let it seep down the injector mounting hole.
Let it soak for a few days, and use it agian during lifting the injectors out.
Sometimes it can be very hard to free an injector, do the following, unbolt the clamp but don't take the bolt of yet, start the engine briefly, compression will free the injector in most cases.
Anyway, take your time, and use a lot of compressed air, penetrating oil and carburetorspray.

Good luck.
