Hello again.
No, normally not much fuel should be lost. Who swapped the fuel pump out? I understand gas is siphoned out to make the gas tank lighter for removal but then should be put back in when repair is completed. As far as the immobilizer system since our tutorial didn't work you will have to use a professional scan tool to reset the system. I've attached pictures below describing the procedure. Hope this helps and let us know if you have any further questions on this issue. Keep us updated. Thanks again for using 2CarPros.
