I think you can't find it because it is not there, grasshopper. Not on the 
Bentley fuel system component diagram for 3B, yet MC and NF have one... 
Motronic cars can adjust the pulse width of the per-cylinder injectors to 
accommodate cold start condition, thus no separate cold start valve. Ain't EFI 

Sounds like you may be having some residual fuel pressure leakdown problems, 
though. Original injectors? Fuel pump & check valve?
