SOURCE: Car won't start or even crank at all.

Check the current draw on the starter when it is cranking the car. If it is excessive it mans the starter is dragging the field with the armature because the bearings are worn out. If the current is not excessive to the starter then it is likely a short in the power cable circuit somewhere.

SOURCE: car was running, electrical wire burning smell, starter makes grinding noise, with the car running, stop the car, starter keeps making grinding noise, with the car turned off, ABS and trac control

You have the polarity of the battery backward somewhere. Did you replace the starter and hook it up backwards. Difficult but possible. Check your positive and negative on the battery itself.
