How much is a pcm modular for a 2005 Lincoln LS V 6,3.0

What is your question?

Put on a new throttle body, it won't start sounds like it's out of gas no signals are getting to spark plugs, coils, and Injectors I'm not sure but the mechanic says it's not the crank angle sensor . The cost for the Pam $1100 I myself price one for half I need to know the actual price , to top it off if that's not the problem I'm stuck with a new Pcm and throttle body and no CAR Help!!
