It would seem so. One way to confirm would be to do the "Plug Swap". If it starts right up then you can figure at least the fuel accumulator. You could also need to clean and replace the "O" rings in the Primary Pressure Regulator, the check valve on the fuel pump, and you could also have a problem with the Control Pressure Regulator (not likely since you say it warms up OK). In many cases it is not one single thing causing a problem, it can be an assortment of things. Check the vacuum lines going to the CPR, make sure they are not leaking and are hooked up correctly. Changing the fuel accumulator is difficult only becuase of the place it is in, it is difficult to access. Use metric open end wrenches and DO NOT kink, twist, or damage the hard lines. Wear eye protection and nitrile gloves. Work in a well ventilated area with the car up high on jackstands or a lift. The fuel pump is not usually the culprit but it is always a good idea to remove it and inspect the insides of the fuel tank. Remove the fuel and wipe the insides. Inspect all of the parts in the tank and replace any that are deteriorated. Replace the fuel filter after using up a tank of gas after replacing the accumulator.
