My 97 Venture 3.4L is difficult to start after it has been operating. First thing in the morning, it starts up fine. Later in the day, when attempting to start the vehicle, it is difficult to start. The vehicle has 95K miles...the wires and plugs have not been changed. Could I have a weak crank positioning sensor? I seem to recall that replacing it on 2 other GM vehicles seemed to correct a starting problem. One other important point, at no time has the Check Engine Light come on, to indicate a problem with the ignition/fuel system. Is my problem simply plugs and wires? Any help is greatly appreciated. Thank you, Joe
