Well for one I’d say most of the people on any forum don’t read the full thread before replying, or they make statements that don’t help at all. Plenty of people on this board have egos and greater than thou attitudes assuming because someone asks for help that they haven’t already checked the most basic issues, including ensuring the fluids were good. Give me a break.
And yet it happens, especially with noobs. My SIL called me one day with a problem one of his AF coworkers was having. He was driving along in his truck and it just cut out and died. First thing I asked was "does it have gas?" I was assured yes it is, there was no way it was out of gas. So I drive 90+ miles up to Abilene, get to the truck and tell him to crank it. Not even a cough. So I pull the gas cap and have him cycle the key, (EFI truck) guess what I hear? A free running fuel pump. My SIL's truck was a virtual clone of his friends so I have both of them listen to both pumps so they can tell the difference.
5 gallons later he's on the road.

Even old crotchety farts can forget things and assume the basics.
