I was told that it could be the fuel pump, I have a brand new battery. Also the fuel filter was replaced but it still will not crank. I was told that the fuel pump can be heard when you are trying to start it. I'm a female so I do not know much about what is going on. Thank you.

    An engine needs fuel spark and mechanical integrity to start and run. It must be determined if the cause of the engine not starting is loss of spark (ignition), or loss of fuel. It is easy to verify fuel pressure and delivery volume to see if that is the problem. If there is no fuel it must be determined if the fuel pump has failed or if the electrical circuit that controls the fuel pump has a problem. It's impossible to guess without being able to do some simple basic diagnostic tests.

    Thank you, I tested the fuel pump relay and it's working fine, and so is the fuel regulator. You could hear fuel flow before the fuel pump was installed last night, now you can not hear fuel flow. It appears as though the fuel gauge is not working now because it reads "low fuel". I have fuel in there, and only a little spilled out last night during the change. Do you have any more suggestions? Thank you so much for answering my question.
