A fuel pressure test will show quantitatively that the fuel system is working within specifications.
I've given Bozzy a volvo k-jetronic fuel pressure test I got from ebay for the club to use, should save guessing.
Test for cold start valve is to put multimeter cables across the pins on the blue plug.
With the engine cold (i.e. not run for at least 8 hours) there should only be 12 volts at the blue plug for approx 7 to 12 seconds with the engine being cranked only. You can prevent the car from starting by unplugging fuse no.1 if my memory is right.
This is controlled by the thermo start switch that is on the left of the water pump as martin said by refering to the brown connector.
Good luck,
NickT.
