I have a 2000 Chrysler Intrepid with the 2.7l V6. The other day I was driving home from work and it just stalled on me. The engine still cranks over but doesn't try to start. I checked to see if there was any power going to the coils and there isn't any. I also checked the fuse under the hood for the ign./coil and with the key turned on and I wasn't getting any power to that either. Also when i crank the engine over i can hear a knocking sound coming from the passenger side of the motor. What should i do next?
