I imagine it came with one but it has not been functional since I have owned the truck.

If you have power to the coil you might have got a bad one from the parts store

Start tracing where the power stops. But at this point I'd put my money on the distributor. It tells the ignitor to send spark to the cap.

Unfortunately when I went through this is was my ignitor. They are expensive. I replaced all the cheap(er) stuff first- coil, distributer...but it was my ignitor. There are diagnostics to isolate what exactly it is, but I don't have that equipment, so I just started replacing stuff...

If it's your ignitor, they unfortunately run about $340, if I remember correctly...

Yes but you can get a used ignitor from $5-$50 depending where you look. I still say distributor.
