Question
1995/eclipse/2-door/automatic

have fuel to the injectors and spark at the plugs but will not start. car has ran great until now when the temp dropped to -10 degrees.

Answer
Tracy,
Most starting problems happen when the temperatures drop that low.  This is usually contributed to a weak battery, weak alternator, and/or corroded battery cables.  If you can, remove your battery from your car and have a friend drive you to an AutoZone, Advanced Auto Parts, or a PepBoys.  Bring in your battery and ask them to load test it and charge it.  If their load test detects your battery is not holding a full charge, replace it.  And if that's the case, replace the old one with the largest battery that will fit in your car, and that you can afford.  

But if the battery is ok, just have it fully charged and put it back in your car.  Also be sure to clean off the battery cables.  You can use some steel wool to remove any corrosion from the cables.
Good luck!
