Can anyone help me i recently dropped a new engine in my civic and ever since im getting bad noise threw my speakers with out starting my car it sounds like the radiator fan and the fuel pump any suggestions.

 

Check your grounds. One is a big wire from battery (-) connects to frame then continues on to the transmission, also the smaller wire from the valve cover bolt to the radiator support near the left headlight, and finally the small ground wires on the thermostat housing, very easy to forget those when swapping the engine.
