hey guys i got a problem with my fuel pump i think. it started when it was cold out last week and i went to go turn the car on and i didn't get that humm that you do when the pump turns on before the car turns over. So i checked all the fuses and even banged on the tank and nothing happened . I turned the heater on in my garage for about 4 hours and then tried to start it and the pump came back on . Now its not running again i just tried it this morning so if anyone has any suggestions please let me know thanks
