truck runs really rough then found a couple bad spark plug wires so changed them ran a little better but still doesnt run as it should. I also changed the fuel pump, cap, and plugs but no change. I also cant get the check engine light to come on but it will not. The knock sensor has also been changed . Any help would be appreciated.Thanks
