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???
