Thanks Kaptain Kuda and Grizzly for your help. The battery was dead after I changed the plugs so I had to charge it. I will check to see if I crossed a plug wire and also check the rotor and cap.I also will try and drive it to see if the computer needs to reset. It did not have the power that I think the 360 should have and got really bad gas mileage. I had a 2002 Durango with a 4.7 and it would have run rings around this one. Thanks again
