My dad has a 2004 1.8S SENTRA that won't start. I was giving him problems a while back not starting up right away or havin to crank it for a while before it would start up. This morning it would not start at all. I hooked up my ODBII code scaner but no codes came up. I have already changed the cam sensor with no luck. I could hear the fuel pump prime up and the spark plugs are wet when I take them out. I did a spark thest on the #4 coil and it is working. All it does is turn over and sputter like it is going to start. I have been reading through various forums all day long and I seem to find is stuff on the CPS. Any help woul be greatly apreciated. THANKS,

 

it could also be no enuf of a spark too much fuel and to little oxygen
