Truck: 2001 Dodge Ram Quad Cab 1500 V8 5.9L

Yesterday i was driving and then all of a sudden my entire truck started shaking, so i pulled over opened the hood and saw that the engine was rocking back and forth pretty violently. I drove home, got in my other truck and rented a code reader. The codes it found were:


P0206
Open Cylinder 6
Injector Circuit Open

P0300
Random/Multiple Cylinder Misfire Detected

P0306
Cylinder 6 Misfire Detected

P0308
Cylinder 8 Misfire Detected

From what i can tell the problem is the fuel inject on cylinder 6, but how can i tell if its the wiring or the actual fuel injector? I dont want to take this in to a dealer to fix it and driving it more than a mile the way it is is pretty much out of the question.

Also looking at the engine, how do i know which cylinder is which? thanks
