hello. well i just got finished replacing the head gaskets, ecm, ignition control module, fuel injectors, and the intake manifold. it ran great for three days. then the fuel pump control circuit went dead (relay coil would not energize). so to get home i ran power straight off of the battery (bad idea, i knew that at the time but i had to get home). pump failed four miles from my house. wiring diagrams are telling me nothing. any clues as to why the control circuit went awol?
