When my fuel pump died the shop connected some type of pressurized fuel can to the injector rail and verified the car would run when it had that fuel. I am not sure about the theft system? I thought the stock one would not let you start the car? but I had a 1997, not a 2000 model.
FWIW, the in tank fuel puml was very expensive!
I think $350+ even with the discount I get from the dealer.
