ok so i had the car running yesterday after it had sat for a few months the fuel pump had gone bad i replaced it yesterday and it started just fine after i had ran all of the bad gas out anyway. i get in it today to start it again and it was making a clicking noise under the dash all the fuses are good brand new battery just bought it today. i thought it was that the battery connections werent tight i tightened them down and now the dome light comes on and the door chime sounds i turn the key to the run position and everything just stops working. what could this be?
