Thank you Danglerb. Unfortunately you missed the question.

I'm referring to the relay, not the injectors. I have the owners and a complete set of OEM shop manuals. None of them describe the operation of the fuel pump relay.

Should the relay "prime" the system with activation of ignition or only run the pump when the engine is running? All of the Audi's and VW's with CIS would prime the system when ignition was turned on prior to starting. My 928 does not.
