Hard Cold-starting 85 Audi 5000

[Dennis Larson <dennisl@operamail.com>]

I am having hard cold-starting problems with an 85 Audi 5000.
I have read the archives but need a few more tips. The only
problem is the cold starts, nothing else. Disconnecting the
connection from the thermotime switch and putting a jumper
wire across makes the car fire up immediately but replacement
of thermotime switch, both used and new, doesn't solve the
problem.

The car has around 250,000 miles on it, a fuel injectors
replaced a year ago and generally is in tune and runs perfectly
otherwise.
