This thread is mainly for me to reference later while I'm working on this, but also have some questions and welcome any suggestions.
I have a 1989 Toyota Van, 2wd. It ran out of gas and would not start after adding about 3 gallons

I jumped the fuel pump test connector and could hear gas running thru the lines, so I know the pump itself is working and getting power. This thread gave me info on testing that:

The van cranks but will not turn over. It gets close but it's like there's not enough gas. Stomping on the gas pedal all the way gets it closer. I'm thinking when it ran out of gas, some rust/gunk got sucked in somewhere in the fuel system and is restricting flow.

I think the following are most likely culprits:
1. Fuel strainer attached to the fuel pump in the tank. Is it a bad idea to only clean/replace the strainer and keep using the old pump?
2. Fuel filter in engine compartment under the passenger seat. I plan on replacing this first. Easier than fuel strainer, so I'm hoping that will do it. But it makes sense that fuel strainer in fuel pump would be affected first.
3. Fuel Pressure regulator. Do these get gunked up? Or is there some other cause of failure?
4. Clogged fuel injectors. I somehow doubt rust would get that far in the system but who knows. Also, don't think they've ever been serviced/replaced


Any other suggestions? I'd like to know better how I can verify fuel pressure regulator prior to replacement. There's also this,
