My 2000 sts would stall almost everytime I drove it once. It would start back up instantly and not stall again. I thought it was the fuel pump failing. I drove the car dry of gas cause my fuel gauge didnt work properly and I put more gas in and ever since the fuel pump would not turn on. I put a new fuel pump in and it still will not power on. I checked the relay and it was working. Any suggestions as to what can be causing the fuel pump to not turn on?
