Use a quality 2 cycle oil and mix it to the oil manufacturer's recommended ratio. Today it is usually 50:1.
Fuel in the USA contains ethanol; try to use up your mix in a month or less. HTH

Disconnect the small spade terminal wires from the coil itself and test for spark. If you do not have spark replace coil. If you do have spark check those small wires for insulation damage and grounding. If wires are OK check kill switch.
NOTE: DO NOT START MACHINE with small wires unplugged! Only test for spark.

If you bought the trimmer new there should be a rod about 6" long and 1/8" thick. Above the trimmer head below the trimmer gearbox there is a hole. You have to put the rod in that hole and turn the head until that locks it from turning.
From there you can screw the trimmer head off by hand, or a strap wrench if it's really tight. It may be left hand threads.
