One, do not jump a crossfire. two, I do not believe a battery sitting hooked up to a crossfire (not started/run) for a year, would ever hold a charge let along charge up. Replace the battery. Then, ask the membership what fuses (at least the fuel pump fuse + ?) to pull that lets you crank for about two or three 20 seconds counts (let car sit for about 30 seconds between cranks). This is for getting the oil pumped up to the top of the engine since the engine hasn't been run for a year. After your confident oil has circulated put the fuse(s) back in that you took out.

About the fuel, IF there is 1 year old gas in it (hopefully less than 1/2 tank or so), add a couple bottles of your best fuel stabilizer additive with a quart of white kerosene, then fill the tank to the full mark with the highest gas station premium you can find (do not drive it until you can be assured it'll run, period, use gas cans to fill it until it is full). You do not want to be on the road and it quits if it started with the new battery). Old fuel may have already gummed up things but I would try this first since if it does run it will over a short period of time clean out any contaminants that may already be there WITHOUT paying someone for a tow (or later a tank removal/flushing and associated). If it doesn't work, it'll have to be done anyway.

DON'T drive it if done with the new battery and the gas issue described above. After it has sat and idled/ran for a while (if idles roughly it is to be expected), rev the engine a few times to see if there are some running/continued idling issues. If not, congratulate yourself that you may have saved a bunch of money. Good luck!
