There is a wire grounding out somewhere. Start from the fuel pump (u know that is good) and follow the wires inspecting them carefully for any chafing or corrosion. It should go up thru the floor around the back of the back seat. Pop the seat out and continue looking at the wires taking the wrapping off as you go. It may be bad under the carpet where water collects from boots and shoes, so look at these areas carefully for corrosion. Happy hunting!!
This normally happens due to short in the wirings.Or if someone has connected a stereo or some other electrical contrivance to the wiring harness (bundle), either under the dash or under the hood.To confirm this unplug the fuel pump wiring connections and insert new fuse.Then start the car and see,if still the fuse blows then its a short in wiring.But if the fuse does not blows then its faulty fuel pump relay or faulty fuel pump itself.So first replace the fuel pump relay and see,if the fuel still blows then its faulty fuel pump.But if the fuse not blowing then relay was the faulty part.The fuel pump relay located on the fuse box under the hood.---------This troubleshooting tips will help you locate the fault and solve it.-------Thanks.Helpmech.
If it is working for a time and just blowing once in a while you probably need to replace the fuel pump. If it blows as soon as you put it in, then look for a short circuit in the fuel pump wiring.
I had a neon that did this in my shop. I found one of the wires to the Oxygen sensors was melted near the exhaust and when you would give it gas the exhaust would flex and short out the o2 sensor.
