i have replaced the fuel pump and the mass air flow sensor... my rover will not start. after i replaced the MAF she ran great for about a month, i drove around town for a little came home turned it off then went out to start it up and it wouldnt start... the starter works just fine but now the fuel pump isnt running and all the fuses are good. i think it might be electrical but dont really know what it could be. any ideas?

 

So when are you going to quit throwing money at it?
Have you checked the crank sensor or the pump relay, without replacing them?
Do you have fuel pressure at the rail when it won't start, how about when it is running?

 

First thing I would do is get back there and back sure the electrical connections to the fuel pump are all attached properly.

 

What Disco Mike said. (about the sensors and pressure)
Check for fuel pressure at the rail. You might have gotten a crap pump, relay might be blown, pump fuse might be blown, pump ground might be compromised....
Did you replace the entire pump assembly or just the pump? If just the pump, did you include the small "sock" filter on the new pump? If you did just the pump and did not put the new "sock" filter on inside the pump housing, you may just have a clogged pump from sucking in the crap floating around the tank as well.

Need more specifics to tell more...
