Question about 1997 GMC Savana
There is plenty of juice in the battery it turns over just fine.I also tried jumpstarting it. I can hear the fuel pump whine when ignition is turned. I tried spraying starting fluid in air intake while turning over and nothing. I doesn't seem to be getting any spark is there a fuse that controls this somewhere that I can check. Just seems strange that one day things are fine and the next there not.
Sounds like you may havw a bad ignition coil or a crank position sensor

A 1999 GMC Yukon has a fuel-injected engine. They are known for the fuel injector lines inside the intake plenum to break and flood the engine. If you are pouring starter fluid and gas in the intake you are only making it worse. replace the injector assembly with the "new improved" injector assembly and replace the plugs, then it will probably start.
This subject is covered by GM Technical Service Bulletin No.: 00-06-04-003B
See GM Parts List below. This replacement Injector assembly is now also available in the aftermarket.

Unfortunately the fuel pump can still be bad. The pump has a check valve on it that wears out. The pump will continue to run but, struggles to supply enough fuel to start the engine. You can buy a fuel pressure test gauge from Auto Zone or that type of auto parts store and check the pressure. You can purchase a fuel pump from them too.

SOURCE: 1999 GMC Jimmy won't start.
firstly where is fuel pump relay as i have never seen a GMC jimmy sorry about that but have you ever seen a foden ?? well the first thing is to check the fuse,if fuse is ok which can be checked by looking at it as its transparent or a piece of wire with a light bulb .across the battery.to find the relay is easy if you dont know where it is,When this piece of americana decides to work just turn ignition on and listen for the click of relay ,then when it doesnt start listen for click again or rather an absence of a click,sounds more like a dodgy pump in the tank or the connections going to it.when it wont start try thumping the fuel tank with the ignition on and if it is a sticky pump you might hear it start then at least you will know where the fault is.Another fault that i have come across with relays is that where the relay is passing a heavy load then its possibe for the contacts to burn inside the relay.When this happens then if it is possible to seperate the relay cover and clean the contacts with a points file (remember them ) or a piece of fine emery paper if the cover breaks taking it apart then use a bit of black insulating tape to repair the cover.Thats assuming the pump is in the tank and not bolted to the chassis near the fuel tank but that design with external pump i havent seen on a europeon car for nearly 20yrs .

probaly a fuel pump its common for vehicles to do that the best thing to do next is a fuel pressure check to verifiy its the pump
