No power to fuel pump, no trouble codeswill run on either,

its not a fuse it is a relay and should be located in your power distribution box under the hood on the driver side of the vehicle. do yourself a big favor pull the tail connector that comes from the top of your fuel tank get a simple test light and test the wires on the plug before the tank have someone turn the key off and on check the wires while they do this usually turn key on it will run 4 a few seconds giving time 4 you to check for power to the tank if you indeed have power going to the tank replace the pump the relay is not your problem if you do not have power going to the tank the relay might be your problem I have also found the key or key switch is malfunctioning and causing the problem. Note if the pump is bad make sure you replace the sock on the pump one little grain of sand will lock the new pump up tight and all the work to replace it will be for nothing make sure to purchase a good pump from a decent parts house like Oreillys and replace the pump sock and a new fuel filter and keep the filter changed at least every 8 thousand miles. failure to do so will cost you plenty in the long run.

Do you know what a fuel pump relay is ? You can check B+ Voltage an control at the relay > Find the relay in the under hood fuse box . Pull the relay out an look on the bottom , you should see four sets of numbers 30,87 an 85,86 ! 30 an 87 are the power side ! One of these will or should have B+ voltage , the other goes to the fuel pump . You could take a piece of wire an jump 30 an 87 , in the fuse box where the relay plug's into . The fuel pump should run ! The control side 85 an 86 , one will have B+ voltage an the other will be open circuit , unless you crank the engine ! The PCM supplies a ground when an input from the crank sensor is sensed. Videos on youtube on trouble shooting an testing fuel pump electrical circuits .

What make vehicle do you have ? Some makes incorporate a FPDM - fuel pump driver module . Fords have a inertia fuel cut off switch. I suggest you go to youtube an check out some basic electrical trouble shooting videos an then go to www.bbbind.com for a wiring diagram an check the fuel pump electrical circuit . Here is a video testing a GM fuel pump circuit . just for instance . GM Fuel Pump Relay Testing If you want to work on modern vehicles you really need to lean basic testing procedures . Not just replacing parts.

You'll have to figure out if it is a fuel or ignition problem to proceed.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, fuel pump blockage, or a list of other things. Is the oil pressure light on ?
If this is a vortec engine, it requires 60psi or more of fuel pressure to run. Have you checked the fuel pressure and is it enough ?

Check fuel pressure. Have you replaced the fuel filter on schedule? Verify that the fuel pump is getting power. Power goes through an in-line fuse, then the fuel pump relay or the oil pressure sensor. (The relay bypasses the oil pressure sensor while the engine starts, but fuel pump power goes through the sensor during normal run operation. If you lose oil pressure, the fuel pump is shut off to protect the engine.) On four-cylinder models, the fuse is in the fuse block (E PUMP 10)
The fuel injectors are connected to the ECM fuse on one side and straight to the engine computer on the other side. Check the connectors and wiring, especially at the injector.

did you replace the fuel filter as well? and check the fuel pump fuse and relay.

• A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
  

Best Practices

• The fuel filter should always be replaced when replacing the fuel pump.
  

Common Symptoms

• A failing fuel pump will not create enough pressure in the fuel system, potentially resulting in a loss of engine power or a "no start" condition. You may also have a lean running condition that can set a diagnostic trouble code and turn on the Check Engine Light.
  
• Fuel pumps require replacement if they leak or begin making too much noise, which is a sign of malfunction. the fuel pump relay is located under hood inside a box with alot of other fuses in it and relay it will be maked fuel pump relay
  

Replace the fuel pump and fuel filter to correct the problem you are having. Without the proper fuel pressure the engine will not run at all. Hope this will help you. You might check the fuse/relay panel for a blown fuse or relay in it to make sure you are getting power to fuel pump before you go to the trouble of removing the pump and fuel filter. Hope this will help you.

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

you say you replaced the fuse, but does the fuse have power? the gray wire at pump should have power when cranking, or for 2 seconds when turning key on. At fuel pump relay, put power onto gray wire, the pump should run if the wiring is good. if it doenst run then ck for power at fuse while power is on gray wire.
