So I couldn't find the switch last night. But this morning I checked it and it is in spec. I will still get another, hopefully in town, but I'm sure that's not the problem.
I completely isolated the cold start injector and it still started without the fuel pump. Add the pump and it floods.
There must be a dodgy injector somewhere. Vacuum is somehow drawing fuel into the fuel rail and when the injectors fire, there is sufficient fuel for it to run, albeit rich. To test this I removed the cap in the cold start supply line and after 15 seconds it stalled out and took a bit of cranking before it started again with the cap back in.
Short of replacing each injector until it goes away, I can't think of a way to isolate each injector to see which is faulty.
Any ideas of how else fuel is getting in?
