our 2002 kia sportage just went dead out of the blue and wouldnt crank back up so we replaced the fuel pump relays that vdidnt work so we replaced the fuel pump and it cranked and went about half mile and quit again so we replaced the coil and still wont crank

If it is not cranking, it could be the alternator has failed. Need to have checked. Have you tried to jumpstart this vechicle? If so what was the result?

it has a brand new altenater also but its turning over just fine its just not starting like its not getting fuel my husband can put fuel into the breather tube and it will start for a minute

It may not be getting fuel. Possibly the fuel filter is plugged or the fuel line itself. Do you hear the new fuel pump charging up the line when you turn the key on? Need to test fuel pressure in the line itself. If you are cranking it but the engine after awhile doesn't smell like it is 'flooding' or the spark plugs are not soaked in fuel, the delivery system has failed somewhere. The best place to start is with the actuation of the fuel pump and test for power.

Not sure how far back their information goes but Kia as a car manufacturer put a lot of great technical information and work shop manuals on line for free for Kia owners. www.kiatechinfo.com .
There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
I hate replacing parts without proving they are at fault! If your engine was not cranking at all it would not be a fuel pump problem, you need to start with the basics make sure the engine develops compression and is mechanically sound develops compression, timing belt is OK! If the engine cranks over the battery and starter are most likely OK. Keep in mind an engine must crank over sufficiantly fast enough for the engine to suport combustion and run. The engine needs three things to start, fuel (gasoline), ignition (spark) and mechanical integrity (it must develop compression in each cylinder to start ie mechanical components must be in synchronization with each other. Check for fuel pressure (you will need a fuel pressure gauge and look up the specified fuel pressure for your vehicle). Remove the fuel hose that goes to the fuel rail and get a friend to crank over the engine to see you have adequate fuel volume (you should have approximately 1 pint of gasoline in ten seconds of cranking). Off course take proper precautions as gasoline is highly flamable. Next "listen" to the fuel injector. Using a mechanic's stethoscope (or use a long screw driver placing the handle end up to your ear place the metal tip end of the screwdriver against the body of the fuel injector), get a friend to crank over the engine while you "listen" to the fuel injector listen to each injector at the same point of the injector body. You should hear "click, click, click" as the injector is electrically opened and closed by the computer. If the injector is not being triggered you will not have fuel getting into the engine's cylinders. Disconnect the electrical connector at the fuel injector with the ignition key in the "on" position, (next position after the accessory position) you should have 12 volts at one of the two wires at the injector. This true for most vehicles but you need to consult a workshop manual for your vehicle to see that this is true for your vehicle. When the engine is running the second wire at the injector gets (triggered) grounded by the computer in your vehicle many times a second controlling exactly when and how much fuel gets injected into the engine. Check for ignition spark. Use caution when checking ignition spark firstly it provides very high voltage (about 15,000 to 40,000 volts) but it is low amperage, it can give an unexpected shock but is unlikely to kill anyone, secondly the spark produced can ignite any flammable gas or liquid (for example gasoline or the gaseous vapors of a lead acid battery). Remove the spark plug wire (or ignition coil if the ignition system on your car is coil over plug type), place an old spark plug with the gap between the electrode and shell of the spark plug "widened" to about .060" or .070" of an inch. Firmly ground the spark plug shell to a good engine ground. Hold the spark plug wire or coil with an insulated pliers and get a friend to crank over the engine while you watch for a pulsing bright spark jumping across the spark plug gap. Look on Youtube for a video on "Check for spark" or Check for ignition spark" I am sure someone has posted a good video clip.
