I have a 1997 Nissan Altima, just replaced the fuel pump that went good. The car started. After we strapped back in the fuel tank, the car now will no longer kick over. checked the fuel and vent lines coming from the tank and they seem okay. checked to see if gas is coming thru the fuel filter and it is. Is there a fuel shut-off buttom that maybe needs to be pushed. I don't have the funds to take the car to the shop yet. Autozone said they thought there is a button on this year of the car, but they did not know where on the car. Help!
