You don't run a submersible well pump unless it is under water. The pigtail wiring may have burnt up; they need the cooling effect of the water and without it, it only takes a short period of power to ruin them. Or... you missed other open or shorts in the cable or don't have the cable to pigtails connected right; good joints. Or you don't have the right pump for the electrical supply or have the pigtails wired wrong. Check out
www.franklinelectric.com (I think it is) for the ohms readings etc. to check the motor and cable for proper ohms and opens/shorts.
