Ok, So I saw my blue harness connector on the cold start valve. Looked correct. Unplugged it, disconnected the ignition (as if engine would start on test cranking, haha). It is about 65F and I haven’t run the engine today. As my wife cranked the engine, the test light illuminated and turned off after about 2 seconds. Signal good to cold start valve. I plugged it back on (using a mirror and light), heard it snap in place, and gave it an extra gentle wiggle.
Enabled ignition, turned key and engine fired immediately! Yay! If anything changes in the next few cold start days of driving, I’ll report back.
Conclusion: While thinking about the fuel pump operation (during process of valve adjustment), I was trying to disconnected the air flow sensor kill-the-fuel pump switch (thinking about operation of the fuel pump, disregard this thinking).
By mistake, I had disconnected the Cold Start Valve but thought it was back in place properly, however, it must not have been seated properly making good contact.
Thank you for your ideas, Targa80, PeteKz, Sigchuck and kevbo.
