Problem in Opel Vectra

First of all, happy holidays to everyone! So, I parked my car in the garage overnight, and the next day I needed to use it, but it wouldn't start. The battery is perfect (new). I took it to the Opel dealership, and they told me it was the injection pump and that it would cost €2030 to fix with a refurbished pump. My questions for the experts are:

Do you know anyone who repairs injection pumps?

Is it complicated to remove it to send it for repair, or is it a real hassle?

If I repair and install it, is it necessary to take it to the Opel dealership to have it calibrated?

So, I have a few questions that I hope you can try to answer. The thing is, it was very strange; it didn't give any warning. The car just stopped working overnight. Greetings to all.

Generally, when those pumps break down, they need to be replaced because they suffer internal wear. Don't take it to Opel; find an injection specialist and ask them. You might save some money on the repair. It's a job if you're not used to it. Check the electric fuel pump that delivers fuel to the engine

We're talking about the fuel pump, right? You didn't mention what kind of car it is, the year, or anything. Well, if it's a gasoline engine, you just replace it, it's in the tank and you access it by removing the back seat. If it's a diesel, you have to remove the timing belt. Obviously, carefully mark the belt so you don't lose the timing. Take it to an injection shop and they'll repair and calibrate it, as much as humanly possible. But this is more complicated; you'll have to bleed the system to get it running, since you have to remove all the air from the system. If you have mechanical knowledge, you can do it without problems; if not, you'll be very frustrated, hahaha.

Kikemec, the pump is the injection pump, the one that supplies diesel to the engine, and the car is an Opel Vectra B Edition 2000, bought in June 2000, with a D-X20DTH engine. If I finally manage to remove it, do you know anyone who repairs and calibrates it, and if I would then have to go to Opel to adjust the electronic data? Thanks for your reply.

If it's common rail, you'll need to use a diagnostic tool for programming. If it's standard injection, there won't be any problems. I'm from Chile, so I don't know where you are to give you information on fuel pump repair shops. I only know of some in Chile, but there are forum members from all over the world, so if you tell us where you're from, someone might be able to help you. Good luck!
