I have replaced the starter, battery, crank shaft position sensor, and the battery cables. At this point it turns over and just cranks but nothing else. I have checked the spark at the plugs for fire and shocked a friend doing so. I have also checked the flywheel and all the teeth look good. I took the truck offroading in a mud wholea few days ago and it has only started 2 times sence. I am running out of ideas and need help bad. If anyone can help I would realy apreciate it. Thanks you can send email to here as well. airassultsnakes at live dot com
