c12 dies then restarts immediatly

850,000 miles

 

850,000 miles is what it shows on odometer i don't know the ecm shows

 

i'm also going to run another ground wire from frame to cab and one from frame to the engine, maybe it's losing ground when truck is moving

 

would that make it die and restart then runs good sitting still even at high rpm it's when the truck starts moving that the problem arises

 

the more we talk about it the more it seems like to me i'm either losing ground or positive wire connection somewhere because of the fact that the truck has to be moving for the probleme to occur

 

found it you were right i pulled the battery box cover off cranked it and pulled on the positive wire going to the ecm and bam it died fixed it by cutting off 3'' put new connector on drove it it runs perfect reason pulling from outside bat box didn't reveal the prob was the + wire was tied to the pos cable to starter had to be moved from inside box I WAN'T TO THANK ALL OF YOU GOOD PEOPLE i appreciate it off to work...........................
