Nissan Repair: nissan quest 1997 not starting, fuel pump relay, nissan quest

Question
My car has been towed 3 times, and it starts at the shop after it has been moved. it will start perfectly, but when parked overnight in my driveway - it will not start the next morning.  it turns over, cranks just fine.  the mechanic came over to my driveway and finally it DIDNOT start for him, so he diagnosed it as a fuel pump.  The $320 charge did not work the next day.  At first, he thought htat it was flooding, then he thought it was frozen gas line, but really it doesnt matter if it is cold or what!  Any ideas for this make of car... he says it sparks,  Hlp..  thanks in advance.

Answer
Check the fuel pump relay.  If the mechanic says it has fire at the plugs one cause could be the fuel pump relay.  Also, check if the factory alarm system is not working properly.  If you have the keyfob be sure to press it to unlock and atempt to start the car.  If that does not work use the key to unlock the door and try again.  Also, check the other key you have to include your valet key.  Drop me a note and let me know.
