Suzuki 2007 Grand Vitara Short 3 doors 1.6

Estimated: I and registered in this forum to get help, my Suzuki leaves me thrown and does not start, everything points to the fuel pump, consult for one of these and tell me that they are of last generation and only original replacement can be installed, and that the value is very high, almost 20% of what my jeep is $ 600 to 700,000
chile fuse that goes to the fuel pump is the Ignition 20 amperes.
-What other failures can be giving me the same symptom (pump failure)?
-Where is the relay that commands the fuel pump in this jeep?
and lowered some manuals from scribd ... (those who hope to upload them, to cooperate) but I still do not find that of my Jeep Grand Vitara year 2007, 3 beancer doors, engine 1.6 please help .....
greetings to this good forum ......... and willing to collaborate in whatever.
