My wife drove our 96 Nissan Altima from work and the radiator over heated causing a hole along the top by the cap. I replaced the radiator connected all the tubes and fan and now it won’t turn, instead makes a choking sound… like it’s going to start the engine, but never does… could it be the fuel pump or water pump or what???
