I suspect the fuel pump circuit is drawing to much power. Do you have something else hooked into those wires(Audio equip?) The fuse is there to protect the relay. Have you put a bigger fuse (bigger number) in there to keep it from blowing the fuse? If not I suspect a bad fuel pump or a stuck fuel pressure regulator(Causing the pump to work too hard- drawing more electrical power) Just remember, its hard to put the smoke back in once it catches fire.

Under you car,just in front of the main fuel filter,why are you replacing it?

I would replace the fuel pump relay, and the engine speed sensor. I would need more information to rule one or the other out, but at this mileage, neither part is terribly expensive, and both have been known to cause your same exact condition

Try the relay first.
It's a lot cheaper than the pump.
The fuel pump relay, is located behind the ashtray, and above the fuses.
In order for you to succesfully remove the relay, you will first have to remove the ashtray housing, which is just a matter of two screws that hold the cigar lighter.
The fuel pump relay, is the one on the right side:)
Don't forget the thumbs up:)))
& Happy motoring

I have no audio at all. The fuse number is 25 when first purchase car so that's what been going with. Bought a brand new fuel pressure regulator 2-3 months ago.
