I am having a problem with the number three fuse and it keeps blowing I did do some tracing and I believe it is on of the 02 sensors, but in the meantime so I can move it ,I am wondering if you can power the pump through the wiring through the fuel pump relay instead of going all the way back to the pump . or if there is any other way of powering it instead thanks for any ideas.

 

Number three fuse on which box, satellite 1, 2 or main under the knee bolster cover. I have three number threes to choose from, four if you count the engine compartment fuse box.

 

sorry I did not mention the satellite 1 position but I am guessing anyone who would ask that question could not possibly answer the above question anyway, i thought the clue about the 02 sensors was a give away.but again there are always people out there who like to waste time pointing out mistakes people make .Ive have learned tons about this vehicle in the last 3.5 years doing things to it keeping a left for dead truck going. yes i can wire it directly to the battery but thought it would be easier to just go to the relay because it is so close to the battery.regardless of where the fuse belongs the question was which wires from the fuel pump relay supply power to the pump the fuse does not matter. thanks for pointing out my mistake and your inability to read plain english.

 

Best of luck to ya.

 

The fuel pump power goes to a couple of relays, and a couple of fuses to control those relays, as well as the inertia switch under the hood.

Just to be clear, the circuits are a bit different on NAS (north america systems) and other models so I think ihscouts was right asking for a clarification.
I spent a lot of time when I first got my disco1 figuring out why the fuel pump had low voltage and then no voltage so I can say that the power comes from all over and the relay on the right front kick panel is a tough one to find as it can be put in any location on the mount.

 

No matter what system is used it is important to determine how much amperage is being pulled by the pump.

Expect to see about 1,5 Amps max draw as it comes upon power up on a D1/Classic/ & Gems P38

If its getting close to 4 amps or above then initial current pull might be blowing the fuse/overheating the relays.

The most common issue is neglect of the in line fuel filter being (plugged) found on the frame rail f'ward fo the right rear wheel. If not check the pump for excessive current pull.

You can check this by using an amp clamp or a simple meter that plugs into the fuse holder.
