Hello my name is Dave.
Hooking up the battery backwards can be very destructive but luckily for you your truck doesn't have a computer so it won't be as bad to repair. First thing I would check for is if you have voltage to the distributor, I have a feeling you won't. It is unlikely that the distributor has been damaged unless you had the key on when you hooked the battery up. One thing you didn't mention is if the engine turns over. If it does a simple test would be to put a jumper wire to the distributor where the red wire goes into the cap. Then try turning it over and see if it starts. If it does then I would start to chase down the burnt wire(s). Another question I would have is what else electrical isn't working, headlights, tail lights, horn etc. If you can check these things and let us know if it starts by powering the distributor then it will be easier for us to help you figure out what else you need to do. It would also help to know how long the battery was hooked up backwards. Let us know what you find and thanks for using 2CarPros.
