QUESTION: yes it has the original engine stock with fuel injetion
This could be a computer related problem, a plugged fuel filter, a bad fuel pump, a defective ignition coil, or a defective ignition module. I would recommend that the computer be scanned first to check for trouble codes then take a fuel pump pressure and volume test if the computer comes up clean. This is an electronically computer controlled machine and the old car simple diagnostic procedures are out the window.
