If the battery is dying that quickly you need a new battery
On the Tahoe K series 5.7L the fuel pump relay is in the engine compartment to the rear of the engine control module, should be identified on the cover over the relays

You have a fuse / relay box under your hood. My 2002 L100 special edition, 4 cylinder, is located near the battery. You have a relay and a fuse in series. A fuel pump operations check, section 4-3 of the Haynes Saturn L-series 2000 to 2004 manual, you can hear a soft whirring sound for 1 to 2 seconds when you turn the ignition to the ON position. I can confirm mine makes this sound when I do this. Good luck with the fix.
Note, I had a crack in my fuel pump, but I took it to an ex-Saturn dealer 4 or 5 years ago because I did not want to mess with it at the time. They had the part and fixed it in 4 hours, but it also cost me $1000 to replace the fuel pump and install a new fuel filter.
I'm sure you know the fuel pump won't have any affect on the ignition. You may need a repair book to get the procedures and wiring diagrams to troubleshoot the ignition system. I am assuming a new coil came with the replacement distributor. Did the cap and rotor get replaced too ? Do you have voltage going to the distributor coil ? Is the rotor turning when the engine is cranked ?
it needs more than spark to run! You need compression and fuel too.Try spraying some throttle body cleaner down the intake while someone cronks it.If it runs on the spray,check the fuel sytem(maybe a bad fuel pump,pump relay,blown injector fuse,etc)
check your spark. If you have spark check your fuel to see if the pump is working. If there's no spark, check your distributor cap. If there's no fuel check your fuel pump relay and also the emergency cutoff switch on the drivers side in the trunk behind the carpet, make sure its pushed in.
My 88 ramvan did the same thing and it was the pickup sensor in the distributor. I replaced it and everything was fine. If the sensor is bad it won't let the fuel pump run or the ignition funtion.
