...it's always a bad ground...ECM's don't go bad unless issued bad ground...as far as your coil packs...make sure that there is good ground connected there...test it....also the main 1/0 battery cable what connects the battery to the chassis ground should be clean and able to pull the big amps through it, and the connection to the motor block as well- these connections may be marginal, creating headaches for everyone-
