Nissan Repair: Nissan Altima 2000 starting problem, nissan altima, body control module

Question
Car was working fine til this afternoon, while I was driving it just turned off
and I couldn't get it to start.  Its not the battery, since all electrical parts are
working.  Engine seems to be starting but doesnt start then.  Some one
suggested that since the last time I filled up the tank, my gas was all the way
to the end, when I filled it back up it might have caused the dust to come up
and cause it to turn and off and then not respond.  Possibly I have to change
the fuel pump.  Any suggestions?  

Answer
Ali,

Try the other ignition key as the car might have lost memory for the key you use normally.  Second, if that does not work check for fuel pressure.  If you have fuel pressure you will need to check to see if the ignition is working.  To do this remove one of the plug wires and see if there is spark when turning the key over.  Check these things out and email me back.  Also, there is a remote possibility that the Body Control Module could be going out.  There was a Technical Service Bulletin on your year model way back when.
