THIS COULD BE SEVERAL DIFFERENT PROBLEMS. SOUNDS AS IF IT MAY BE A FUEL DELIVERY CONCERN. THE ONLY WAY TO DIAG. THIS CONCERN WOULD BE USING AN UPDATED SCANNER FOR THIS VEHICLE. THE "SVC BRAKE SYSTEM" IS MOST LIKLEY CAUSED FROM THE NO START ENG CONCERN. IF I WERE TO TO TAKE AN EASY GUESS, YOU CAN CHECK YOUR FUEL PRESSURE REGULATOR, IT MAY BE LEAKING. TURN KEY TO RUN, DISCONNECT VACCUME HOSE @ REGULATOR. SEE IF FUEL IS COMING FROM REGULATOR, IF THERE IS, YOUR REGULATOR IS FAULTY. YOU MAY ALSO HAVE A DEFECTIVE FUEL PUMP, BUT A GUAGE IS NEEDED TO VERIFY.
