My wife's Crossfire has been sitting for a year. I need to jump it to move it to a different location and look at the caution lights to diagnose any issues so I can fix and sell the car.
-Is it ok to jump the car just like any other car?
-Will putting an additive to treat the old gas in the tank hurt the engine?
Thank you in advance.

 

I would suggest charging it with a charger, negative cable removed, before starting.

 

Nothing can treat old fuel and I also recommend a full battery charge opposed to a jump start

 

I would charge it fully as described above or replace it with a new battery

 

A full charge is better than trying to jumpstart. If the gas is a year old, I would run it empty once running. I would start mine on year old gas much older I would probably drain the system. When you refill tank add a stabilizer in case it sits for another year.

 

If it's time for a new battery I would buy it or fully charge the old battery rather than jump it there have been electrical problems from jump starting also put a large can of Seafoam in the gas tank, top it off with a good grade of premium gas and drive it

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!
