Bleeding fuel supply

My 930 has arrived on a boat. It wont start. It coughed slightly then died. Not sure if it had enough fuel. Fuel gauge close to E. Put fuel in. But does it need priming. My SC requires lifting the air plate til the injectors load up. How do we do similar with the 930 - or what is needed if it has run dry on fuel.

Gently move the ignition switch toward start. Just before the starter engages you should hear the pumps running. Hold the switch there a few seconds before starting. It's a recirculating system with a regulator, so this should be all the "priming" you need. Others feel free to correct me if I'm off here...

We have been discussing pump behaviour on Rennlist.

To make sure the pumps are on you can simply disconnect the connection going to the CIS flapper plate. This will make the pumps come on if the ignition is on.

You are correct. To bleed the fuel injection you need to manually move the air flapper till the injectors squeal. Just like the SC.

Thanks guys - I followed the first advice and expected it to prime itself. It finally did, after a lot of coughing and spluttering and starter motor cranking. Finally fired on one or two, enough to turn it over without starter motor. Slowly the others came to life. I think I will try depressing the air plate next time.
Thx
Alan
