I was looking at my Bosch distributor-type injection book and their chronology of improvements over the years. I realize your pump is Japanese - I'm wondering - is it the Jap Diesel KiKi VE clone like on my Isuzus?
Also, what year is it?
I figure the Jap clones would follow, to a degree, the Bosch changes. In regard to cold-advance and fast-idle controls - they show as the years certain features first got used:

1975 - Cold Start Accelerator - KSB
1982 - Temperature Controlled Idle Speed - TLA
1987 - Pneumatic Idle Speed Increase - PLA

I'm not familiar with any of it - mainly because I've never had a problem except with the coolant-sensor controlled fast-idle on my Isuzus. My Volkswagens - with the genuine Bosch pumps - have never had a problem - but I suspect, some control is manual. Both have a "cold-start" manual pull cable - works like a choke-cable for a carburetor. I don't even know what is does - since I never had a problem. But it's effect is - faster idle and seems to advance timing when cold. It might also add extra fuel - maybe I'll have to read the book sometime.
