My 1992 stanza keeps blowing fuses for the fuel pump. It had a 10A fuse in there and if blew 3 of them within 30 seconds. Then, i tried to put a 15A in there and the same thing happened. Is the fuel pump bad, or is it an electrical short, or what is it! I've heard a few different things. What's your opinion? HELP ME!!! =)

Racer123 has it correct. Disconnect the fuel pump connector near the gas tank and re-install the fuse (this takes the fuel pump out of the circuit). If the fuse still blows, you have a pinched and shorted wire between the relay and the connector you disconnected. If it doesn't blow the fuse and you now re-connect the fuel pump connector and the fuse blows - you have a shorted fuel pump and it must be replaced.

Its one of three things: Fuel Filter is clogged (from debris and rust in the gas tank or old age) and causing the pump to overload, the fuel pump has developed an internal short and its blowing the fuse, or lastly its a wiring issue going to the pump.
1) If you havent changed the fuel filter in a while or you think some contaminants are in the gas tank, then change the filter and have the fuel tank cleaned or replaced.
2) Run an auxillary set of power wires to the fuel pump with a 30 amp fuse in there, and look for any wire chaffing in the trunk or anywhwhere else a wires could have been damaged or exposed. Fix wiring as necessary
3) If its still popping fuses after the auxillary wiring is run and tested, then time for the pump to come out and a tank inspection and/or cleaning. Its also possible the tank is too rusty and will need to be replaced.

You answered you question, either there is a short in the wiring, or the pump itself is bad. When a fuse blows, whatever it is controlling is trying to draw more amps than the fuse allows. The fuse is a protective measure for you and the part.
It seems your fuel pump should not have more than 10amps of power to it. If there is a short, and the fuse didn't blow, then your pump could be damaged do to too much ampage making it to the pump.
I would start with trying to isolate the short, and repairing it. If there is no short you can find, then look into the pump itself.
You may want to take it to a professional, as they have the tools to isolate fairly close to where the short may be. But, this could also be repaired by yourself.

Remove the fuel pump relay then retry fuse. If ok then unhook fuel pump wire and reinstall relay.If fuse stays good then fuel pump is most likely shorted out.

IT SOUNDS LIKE A SHORT (CIRCUIT) TO ME, TRY REPLACING THE PUMP OR RUN NEW WIRING TO THE OLD ONE, YOU MIGHT HAVE A PINCHED WIRE.
