fuel pump?

When you first turn on the ignition switch or crank the engine over there is no power to the fuel pump. I switched the relay but nothing. If I hook up my scanner and manually turn on fuel pump circuit then I do. Dont have any wiring diagrams to work with. So need those or if someone has had this problem would be thankful for any help.

Non communication with scanner common in PCM failure

Ok well we replaced the PCM and now the car still wont start we tryed to have it flashed but the dealers tool couldnt communicate with the PCM could this be caused by the throttle position sensor? Or could this be caused by a short in some wires?

Wiring is at fault. Is fuse still blowing? Data link wiring needs to be checked. Have wiring from Data Link Connector to PCM
