Okay here is the scoop (if you dont want to read this thread:http://www.shoforum.com/showthread.php?t=61137)

1) 500 mile drive car ran perfect, sits overnight, no fuel pump prime next day.
2) Code 95 is thrown - Fuel pump secondary circuit failure ( ambiguous code - not very specific)
3) No power to inertia switch
4) IRCM clicks when fuel pump circuit is jumpered
5) Pin 5 is not getting power
6) Pin 8 is getting 12v

I did the IRCM pinot with a voltmeter (with the fuel pump circuit jumpered). Here are the results:

I need direction. Why is pin 5 not getting power, even when I jumper the fuel pump circuit? Does anyone have circuit diagrams for the pin 5 circuit?
Would bad 02s short out the fuel pump circuit for some reason? How about the AIB valve?

Any help is greatly appreciated.

We'll now it seems like Im getting a full 12 v to the inertia switch. The car fired a few times and then died, so it seems like the fuel pump is dying. I tested the pink wire to the pump and its getting 12v so I think its time to change out the pump.
