Anything that is not permanently attached to your vehicle is not covered under your auto policy. If you have a homeowners/renters policy, there could POSSIBLY be coverage there.
i was hit on the driver side front fender is my frame totaled
It is the fault of driver who was initially at fault. In this case it would be the driver of the first car, because it was because of him that the second car hit the third. if the car is totaled, that's the driver's problem
Its your fault
If you want to collect otherwise you need a lawyer to sue for damages
There is no deductible for liability claims.
Presumably because the other driver's insurance doesn't cover that expense. Check into your own insurance policy to see if maybe your own insurance does.

Have the car appraised.
If you have any way of finding the other driver, be it through witnesses, or other sources, then they will have to pay. If you can't get said information, then sorry, but sounds to me like you're out of luck.
You uninsured motorist coverage, if you have it should handle the gap. Otherwise, you can sue the driver that hit you for the difference.
If the driver was uninsured or only had liability insurance, they would be liable to still pay the finance company back or face a lawsuit.
