The car obviously doesn't do a lot of kays, having done only 55,000 in eight years; so I'm guessing it sits around idle for much of the time. From the compression figures it could be that the valves are not sealing properly through lack of use. I doubt that you would need a new engine, or a major repair, but if it's now going I would suggest you take the car for an extended drive. If it's not going then you might be faced with taking the head off and checking the valves.

I doubt it is a fuel pressure problem, if it was you would have trouble all the time, not just when the engine is cold. It sounds like the cold enrichment is not working, so have that checked. As for the garage tracking a problem can be a challenge and many a new part is fitted that doesn't do the job. The best thing is to return it to the garage, tell them they haven't fixed the problem and ask them to check it again. If you're not sure they are competent to do the work tell them that you approve of any parts before they fit them.
