Answer
Before condemning the fuel injection system you should try and retrieve some fault codes, if any, from the engine controller. Try this first, cycle the ignition switch as follows, On-Off-On-Off-On and leave on. Watch the window where the mileage is displayed, if there are any fault codes in the engine controller, they will be displayed there. You will be looking for a P followed by 4 numbers, such as, P1234. Write down the codes and repeat the process to double check what you saw. If no P-codes are displayed then you may need to get a professional involved. Which you may need to do in any case, but let's start with trying to retrieve some codes first.
