Thank you @ngoma. No, it's a different shop and I completely lost trust in it after even the replacement injector was faulty. I will return the whole batch and buy somewhere else 👍

And so, after a full day of work at -1 degrees, I could confirm it was the pump after all 🤬
Here is a video taken yesterday of a cold start with the "refurbished" pump: https://www.youtube.com/watch?v=_l-emfG-GzQ And here one with the old pump, taken after I swapped it back in: https://www.youtube.com/watch?v=Q6QqJHvTogs So much time wasted because of this.. at least I know what the problem is. It's a really bittersweet feeling though, since I spent so much time and money on this engine and I now know it should have started without hesitation on the first attempt almost a month ago. All this fiddling and letting it run as it did cannot be good, but it is what it is. I'll now see what the seller has to offer but I'm leaning towards getting my money back and heading somewhere else 😕 Thanks again everyone for the invaluable tips, I likely wouldn't have managed without you guys 🙏 |

So the injectors and the IP were both bad rebuilts, from different vendors? List them here to warn others to avoid them.

That is a major bummer but very good to hear it runs well now and the mystery is solved. It sounds good and healthy!
There is hardly anything more frustrating (or confusing) than new parts that are defective. Especially difficult to deal with in a situation like yours, in a major overhaul where many things on the engine have been replaced all at one time -- very hard to pinpoint the particular guilty component when there are so many possibilities. Nice work getting to the outcome and thanks for sharing the whole story, it will be a good resource for others in the future. Pretty sure you can be confident the engine will be fine in the long term, not likely to see any lasting effects from everything that happened. A good hard run once installed in the vehicle and after the initial oil change will certainly be therapeutic for it.

Injectors were from here: http://www.bugetti3000.de/de/ And the pump from this eBay seller (from Latvia): https://www.ebay.de/str/neringsde |

I will now bring my old pump to a local shop for a general overhaul, I probably should have done this in the first place. I will give a (hopefully final) update once I get it back and have the chance of installing it back. Then, the engine should be ready to go into the car |

Otherwise, unless the shop and technician is confirmed experts with verifiable recent track record, opening up the IP can create more problems that didn't previously exist.

I was also considering just using it as-is, but with everything else being in like-new state, I didn't want a pump leaking on me after the first few thousand miles. I surely hope the shop I brought it to will do a proper job. They are a Bosch certified diesel service center and every other shop where I live pointed me to them. Crossing fingers 🤞 In any case thank you for the hint, now I know they can still mess it up and I'll be on the lookout for problems. |

Pump is back from the shop and mounted on the engine. Here's a final video of the engine running nicely : https://www.youtube.com/watch?v=H-aIrUv3lA8
Thank you again @ngoma and @v8volvo for the help along the way. Forever grateful 🙏 |
