Started last week after 4 hour ride to vacation at beach. Started like a dying battery. Click 6-8x then turn over and fire. Went to one click and no start. Got a jump ran normal. Went to get jump box and volt meter. Battery tested good. Alternator putting out 14.3. Even went to let parts store load test battery and alternator. I’ve checked relays fuses grounds cleaned battery terminals. Someone mentions possible ecm and also was told the solenoid could be bad and extra power from jump box it pushing it on thru. On way home after jumping it off ran fine first 30 min then dash started going black. Radio cut out door locks click then powers right back up. Did it maybe 14-15 times all way home. Also last hour of ride abs traction control lights came on and never went off. No work has been done recently to truck other than an exhaust hanger being welded on a week prior to trip. Drove it all week after weld no issues. Now that I’ve been messing with it here and there lights flicker inside when door is open and alarm randomly goes off. Also the alarm doesn’t set when key fob is hit second time. Anyone had any similar issues? Going to pull all grounds and clean them this time. I have another ecm but it isn’t tuned for this cam. Thinking I could swap it to see if I can get it to start.
