My car stutters frequently like it has no gas and theres a loud hum from the back of the car when it is stopped. It is a 5 spd 86 GT with a rebuilt 5.0. I'm guessing pretty uneducatedly that it is the fuel pump but I know that people here might have alot more to add and other ways to differentiate between what problem it might be.
