[QUOTE="Gilaguy23, post: 430981, member: 19498"] Optimally you should have the same voltage throughout the entire vehicle which is typically between 13.8 and 14.3 when its running. For starters make sure your charging system is up to snuff. In a nut shell the lower the voltage the more amps are required to do the same job and at some point if it drifts low enough things will stop working. In your case Id suggest you have a bad ground or several of them. A bad ground will cause heat, heat will cause more resistance and lower voltage to the pump and other systems. Cleaning ALL the grounds is where Id start for one. [/QUOTE]
