You have bad fuel injectors for sure. That is exactly what happens when fuel leaks into the cylinder and the car is started with one or more cylinders running too rich. Furthermore, if fuel is leaking in through the injectors then air is also getting into the fuel line resulting in stuttering, shaking, engine turning off.

You can check the pressure by using a ROSS-TECH VCDS if you know someone who has one or are willing to spend the $349 to get the CAN/OBD-II reader.

Also, leaky injectors can increase the hot/cold starting times. One way to check for leaky injectors is to remove the spark plugs and see if any fuel is leaking into the combustion chamber after the engine is shut down. Drive the car so it gets warmed up thoroughly and then shut off the engine and wait about 30 minutes to an hour. Remove the spark plugs and look down into the cylinders combustion chamber using one of those fiber optic flashlight attachments that will allow you to insert the fiber optic light pipe down into the cylinder through the spark plug hole. Using this light pipe you can actually see puddles of fuel inside the cylinder. If the spark plug tips are wet with fuel, this of course is another indication.
