Did some work today on the engine.

Started it up, it was actually running fine for awhile without the AFM being hooked up (Yeah, I'm an idiot).

Is this indicative of anything? For instance, a big arsed vacuum leak?

 

No, not really. Though it is rather odd since the fuel pump cut switch is in the AFM. Is the initial set coupler jumped?

 

I would think you could start it up with the fuel pump connector jumpered and the AFM unplugged. Never tried it. But I did forget to plug my AFM in the other day, and it wouldn't start up for me since the fuel pump was off.

 

No.
