Sounds like the fuel pump.Hi Naughty Nate and Automender1234,
To answer your above question, yes it will start cold, but it's a very hard start, sounds like running on a couple cylinders, then immediately dies. So on to the starting fluid test:
I pulled the rubber bellows off at the throttle body, rammed a little piece of wood in there between the bellows and the body to keep the rubber a couple inches down out of the way, then I could see the plate, opened the plate and gave it ~ 5secs of starting fluid back in there, reattached the bellows, started it, and I got about 5 secs of a good rev, but it sounded like a smooth rev with all cylinders firing, then it died immediately when it ran out of ether.
I asked above, and again now, do you need a video of that fuel pressure tester winding down, and down, and down? If not, I'm open for suggestions on some next steps.
Thanks again for putting up with me on all of this. At least we can do this at our leisure and we're not sitting at a rest stop on the turnpike with screaming kids in the back seat. Amen to that.
Regards . . .
