If you have a multimeter, connect it to your battery, and select an appropriate DC voltage range. On my multimeter, I use the 20volt setting.
If your battery shows 12-13.8 volts, then it is not the issue. If your battery voltage is low, then you will probably need a new battery. A flat battery can also indicate that the alternator is not recharging your battery properly, but it could also just mean that your battery is old and needs replacing.
If your engine wont turn over, and if your battery is good, it could be a faulty starter motor.
Those jump start packs need to be charged often, or the battery inside them can stop working. It is possible that your jump starter pack is also broken.
Try jump starting the car from another vehicle, with jumper leads. If you know your battery is dead, you could also just replace it with another one.

The check engine light is a warning to let you know something needs your attention to be repaired I would try getting a jump. Could be a bad battery. Lets get the battery charged and tested. Cold weather will stop your car from starting if you have a weak battery. You dont need to tow the car just take the battery to Autozone or Walmart to be charged and tested for cca...cold cranking amps
