Help! L200 Won't Stay Running..

[tfmc369]

my wife has a 2002 or 2000 l200..
she went to start it yesterday and it was completely dead.
tried jumping it and it turned over, but died after about 2-3 seconds.
took the battery out and got it checked. it came back replace battery..
bought new battery & replaced it the next day. the car started and ran for about 3-4 seconds and died again.. everytime it starts, it runs for about 3-4 seconds and dies..
is it the fuel filter, fuel pump, alternator?
has ne1 else had this kind of problem?
any help asap would be greatly appreciated.

thanx in advance

sounds like a fuel pump issue, or wiring for the pump. Could also possibly be the mass air flow sensor.
