I was going down the high way just fine and Jeep gages went kinda crazy and then died! Check engine light came on about two days ago, I figured it was the fuel pump cause I didn't hear it hum when I turned the key over but then again I was on the side of the high way, changed fuel pump. .... nothing. Turns over great but wont fire up! I pulled the coil pack rail and a spark plug I'm not getting a spark in any cylinder so..... is it the cam sensor? If so is it that little sensor right above the oil filter? Please any ideas would be helpful?
