I switched the ac fuse with the fuel pump fuse got under the back of the truck and had somebody turn the key on i heard the fuel pump kick on but when i pulled the breather box off the throtle body i couldnt smell any gas after several minutes of turnig it over

could be a number of things. To check fuel pump turn key to on position ready to start but don't crank it and listen for the fuel pump to whine then kick off. If you hear the pump check for spark. Your issue could be crankshaft position sensor or injector problem or a number of things. I am limited on guesses not knowing make ,model ,year , or engine displacement

Check connections on field pump relay in fusebox under hood look for corroded (green) wires replace corroded wires and conectors .temp. Fix maybe clean if so it will come back. 20 years old due you live in snow area were they salt the roads?

the clicking noises you are hearing are the relays powering up, that is normal. with somebody in truck try starting itw ith somebody under truck at the gas tank, take a rubberm allet and bang on the tank in the center of it while cranking, if it starts you need a fuel pump. make sure you have gas in tank the sending unit on the fuel pumps go bad all the time.

ok so ntheres power at the relay is the relay bad get a piece of pretty heavy wire not small speaker wire a little bigger than that about 6 inches or so strip off both ends pull out fuel relay turn key on position stick wire down into slots where relay plugged in one of these is a ground so it will spark so u know not to stick it back in that one but check alln rest until you hear the fuel pump kick on or get under car at gas tank unplug fuel pumphave somebody turn key on and off and u test it with test light ton make sure you are getting power to pump if you are then pump is bad

OK several things to check, is there power to the fuel pump, check as close to pump as you can? and did you check the ignition coil?

you didnt list the year make or model, only fords come with fuel shut down switches and they are located in diffrent areas, behind left kick panel or in the truck on the leftside or rightside and then the right kick panel but only ford has this, good day, if you want to send the year make and model i will be able to help you further.

Here is the manual
FUEL PUMP SHUT-OFF SWITCH After a collision, if the engine cranks but does not start, the fuel pump shut-off switch may have been activated. The "Fuel Reset" indicator light will illuminate in the instrument cluster. The shut-off switch is a device intended to stop the electric fuel pump when your vehicle has been involved in a substantial jolt. 1. Turn the ignition to the OFF position. 2. Check the fuel system for leaks. 3. If no fuel leak is apparent, reset the fuel pump shut-off switch by pushing in the reset button. 4. Turn the ignition to the ON position. Pause for a few seconds and return the key to the OFF position. 5. Make a further check for leaks in the fuel system.
The fuel pump shut-off switch is located in the passenger's foot well, behind the kick panel.

Well i would change the fuel filter first. Then if that doesn't fix it there might be a reset button on the inside of the trunk for the fuel pump actually look for the reset button first. If you don't have one there is a relay switch under the hood sometimes they fail. You have three Ac,Fuel pump, door locks. The way i do it is turn the key on have some one put there hands and feel for the switch to work when you engage the power locks mark it with white tire crayon and feel for the ac when you turn it on it will still click even with the engine not running. mark that one also, Now the last one has to be the fuel pump relay turn the key on and it should click. if no click is heard? You have a bad fuel relay switch. replace it. If you feel the click and hear it? That would mean the fuel pump is bad. And these are in the tank. But please go with the easy stuff first. it might seam a waste of time checking the relays and marking them but i always fo this and mark them. cause you never know when your gonna need to find the relay something.
Good luck!
Hope i helped.

try resetting the inertia switch located on drivers side way up under the dash,with a red button on top,maybe you kick it or hit the body hard enough to kick it off,also check the fuel pump relay under the hood drivers side ,i think brown and black relay box over wheel( inner fender)..and check the fuse,and new fuseable link

check the fuses inside on the right hand front kick panel
