I was thinking about your issue and it will be good to check control pressure. It may be that it is stuck at one pressure so it kind of runs ok warmed up. But it is at too lean of a mixture for cold running because the control pressure is high.

When I bought my turbo in 1995 it had a cold starting issue where it would start and them immediately stall. It would do about six or seven of these in the morning winter startup and then run ok after that. Hot starting was ok. After about six months I had bought my IPD gauge. The control pressure regulator was clogged and control pressure equaled system pressure. So even the warmed up mixture was too lean.
1982 242 turbo. 340k miles. Good stuff and lots of rust.
1993 245 Classic, 420k miles, enem V15. IPD bars and chassis braces. Simons sport exhaust from Scandix. sbabbs ezk chip. Been a good road warrior. Genuine Volvo rebuilt leaky M47.
