No power to ECM?

Oh, and that other one that’s on the fuel lines is in fact a pressure regulator.

The BAP and MAP are not something that you find together on the same engine. It’s either one, or the other. Not both.
And that’s it, so if you have a BAP sensor and no vacuum line connection to it, your set up is correct.

Absolutely! I’d forgotten about that but people definitely have suffered from spiders and mud Dauber plugs before. Not to mention the sensors just failing like any other electronic device.
Probably not big enough for a mud dauber to take interest in, but that was the first thing that I thought of when you mentioned bugs.

I agree with Paul regarding the vacuum caps. Do yourself a favor and tap each of those unused lines and JB weld a small pipe fitting inside. On my rebuild, its taken me about 10-12 years, and in that time I had the cheap caps on the vacuum lines. Even without the engine operational, those caps deteriorated in my hands after the few years of sitting.

I use vinyl vacuum caps. They seem to hold up well.
