Ive got a truck here, that when its been running, and shut off for 20 mins or so then started back up. It starts to run away. He says that he can cut it off by the key, then usually restart it without a problem. It has a new injection pump, and lift pump. And is running a Edge Comp. Being mechanical injection. This shouldnt be caused by the Edge should it. Sounds to me more like its the injection pump. Anyone had this problem, or heard of this problem. Any suggestions. Thanks

 

I would check the apps voltage. run it, shut it off when it would normally do it and check it again. also try unplugging the comp and try it. take out any variables.
