cold start valve csv not getting power?

[body_infinity]

Hi all and thanks for all the help so far..i am currently working thru my ignition system on the 71 280se m116 3.5 engine…the problem I am getting is that I am getting no power going to the cold start valve (CSV). I have checked other posts here and on other sites but no real answers to my problem...

I have done all the tests as per manual
(ie) have grounded the csv “w” terminal which should trigger the csv but again no power, checked the terminal on the TTS all good I am getting power to the TTS "G" terminal while cranking which as per the manual is the heating element so looks good. so I am thinking of a relay problem that sends the power to the csv?? my question is where the relay is for the CSV or how the csv work? I think I read that it gets ground from the TTS (w) terminal but as I have grounded this it continues not to have power

I did see two silver cylinder relays attached near the ecu in the engine bay (2x 30a and part number 000 542 9719 they are dated 1971 wow original relays) I know one is for the csv but what is the other one for??? info /diagram would be great..thanks heaps ;-)
