The way I understand it, it fires the cold start injector when it senses the vacuum drops off, (ie opening of the throttle plate) to compensate for the instant lean condition.
It does have that. The PO set up the cold start injector to always run and I have not been able to figure out how to undo that so I came up with my home-brew solution to get around that. I suppose that would be the smart thing to do.

Mars, have you hooked up a CIS fuel pressure gauge to this thing yet? You're welcome to come by my place and use mine. Bonus: I have lots of CIS spares to fiddle with if necessary.
I will give that a shot, but given that the 5th injector is set up to work not-as-standard, I'll have to do some re-wiring. I would really appreciate a helping hand. I'll PM you after checking into that.
