The other day I got into my truck, after I filled up and drove it home then started it back up n started driving and about 10 minutes after drivin I took off from a stop sign not getting on it hard at all and it gave a hiccup. It started running real funny and I slowed down and pulled to the side of the road and it just died. I pulled out my efi live box and scanned the code po336(crank position sensor). The truck would not start back up or run if it did it was for a few seconds and sound like only 2 cylinders were firing. I had my buddy come load me on a trailer and got it to my house and first things first I grabbed a wrench to turn the crank by the harmonic balancer bolt. NO COMPRESSION it has very little resistance. I changed out the sensor with no change in startin the truck. Did I snap my crank? I was just about to start the drag racing season this year too :/
