if its cranking, the battery is fine. what you need to do is find out if its spark or fuel your not getting now.
take a plug wire off the coil, and prop it so is like a 1/2 inch over the coils where it was plugged in, then crank the engine, look for a spark to jump to the wire from the coil.
if you have some starting fluid spray that inside the intake while cranking the engine if it fires up your getting a spark, and need to find out why the fuels not getting there.
did the air bags go off? that may have something to do with no fuel. if its a no fuel case.
on the fuel rail is a valve, like a tire air valve, but fatter, find that, and push the center in, put a rag over the valve, then push it with a screwdriver. the rag will keep the gas from shooting in your face, if theres fuel pressure. if no gas shoots out, that means your not getting gas.
