Audi 200 mc2 residual fuel pressure

[pdooley]

Every CIS car I have owned eventually gave me hot or cold staring issues.
Instead of finding and fixing the real problem, I always just installed a
circuit to activate the CSV with a momentary push button switch.
Then while cranking I would just push the button.
Worked like a charm, even if not the right way to do things.

Guys, still issues starting the car!

It's ok in the day but it's a bit hard in the morning.

I have fixed a nubmer of things and checked more! Including stuck  
carbon canister valve, misc air leaks

Residual fuel pressure is 3.2 bar after 20 mins, 2.8 bar after an hour  
and 1.4 the next morning. Is this normal?

Csv is not leaking

Check valve swapped and no change

Injectors are 2 years old with 29k miles ish

No puddles of fuel under the car

New fuel filter

Runs rough with the dipstick out

Duty cycle at 40%

Everything clicks and buzzes durin the output tests

During the day it fires after 2 or 3 cranks then tries to die for a  
couple of seconds then is fine

Any ideas

Geraint
