In the manuals they state that before changing out a fuel injector you must reduce the fuel system pressure. Other than opening the tank cap, how is that done?

Well, I removed the cold start injector with a minimum of fuel spillage. Once I changed it out with a clean one, I noticed a slight improvement in cold starting.
When you disconnect the lines, you'll get some residual fuel out. Sounds though, like you have a faulty pressure regulator and or lacking fuel pressure due to a faulty pump/regulator.
Anything that helps to improve the proper atomization of the fuel spray will help "cold starts".
I finally changed out our regulator(wt 94k on it) this past year and ethanol had killed it. The thing would barely hold any residual pressure. It's amazing the truck even started and did not foul out the plugs(or worse, wash down the cylinder walls with fuel).
