Hi Joe,
 
	I'm back after many attempts to fix my S Type. Took it to a dealer and they said it was  the fuel pump. I replaced it, and still no joy. Even changed the throttle sensor. Buggers  were not interested in me giving them the info you sent me. Back to square one. Could you help me figure out how to deal with the TACM to PCM failure. I'm handy but not that comfortable with electrics.
 
	Thanks again.
 
	Michael
