...$4000 to fix? The dealership wants to replace the fuel pump, lift pump, and update it. They still cannot guarantee that the computer is not dead. My dad will not pay that and can get another truck for that.
No, this is what you should do.
1. grab sledge hammer
2. pound the shit outta the car till its all mashed up nicely
3. Call it a day and tell your dad some physco attacked your car and u need a new one :]
