6. Pull out shutoff lever and push back in. (Does something important)
6. Put throttle to full
I am sure you may have got this around the wrong way.
For the cold start procedure, you should first set the throttle 2/3 to 3/4 and then
pull the stop out and push it back in. This sets the fuel supply to "excess". As soon as the engine fires and runs, the "excess" setting reverts to normal running.
I have the VP2003 in my boat, and only use the cold start procedure for cold days (when else?).
Before getting my engine "top end" overhauled, I had to decompress and turn the engine over for about 15 secs to get some fuel and oil to improve compression. I then reset the decompression lever to normal and (usually) the engine would fire after about 5 secs. Eventually, it would not start at all - hence the overhaul!
After the overhaul - glazed bores, worn rings, burnt valves and seats, blocked water injection elbow, injectors overhauled (only one out of the 3 were spraying) - the engine now starts quite often without the cold start procedure.

Volvo cold start procedure is to open the throttle to half way THEN pull out and return the engine stop. I understand that fiddling with the throttle setting after pulling the Engine Stop resets the system.
Hi, you are correct, that is what the instruction manual says. However, once the throttle has passed the halfway point the cold start is activated by pulling and returning the stop button. If the throttle is not moved it will start but at a higher RPM. This may not be good practice but some engines require this technique-my one did.
