Whats the code?Possible bad ground at the lift pump which is hidden behind the starter. This requires to remove the starter to service this ground. (At least on the 02 dodge).Possibly a bad lift pump with a heavy load that is pulling the voltage odwn on that circuit because of mechanical problems internally.
