i have a 2000 gt. i just swapped out the motor with a junk yard one because it was blown.for some reason the fuel pump does not seem to be kicking on. i changed the pump i changed the fuel pump drive modulator and still nothing. it has an aftermarket viper alarm. not sure if this could be the problem. i cant locate the PCM. might i need to change that? i really feel like this is a computer issue of some sorts. any help would be great.
