pretty sure the 73 was carburetted - if it stopped on a grade with low oil, most likely you had partial seizure. once it had cooled, it released and you were able to continue.

not by your previously stated criteria it wouldn't - a switch can still "work" when pressure drops. but it can be out of spec as to /what/ pressure, and the diaphragm leakage mentioned by steve w is exactly the kind of situation that illustrates this.
on the subject of pressure, if you will be so good as to link to a tool that will test such a switch with regard to switching pressure, i will be much obliged.
Wait a minute, you're telling me that it's possible to have normal oil pressure in a '71 Vega?

GM S series P/U and Blazers, Full sized GM trucks. Nissan started it on many of theirs in the late 80's. Ford has used it on the F series from around 96 or so. Not on the diesels though. Most of the German makes have a dual system BUT 1/2 of the ones I have worked on don't operate until the oil pressure is down in the 1-2 pound range.
The Vega powered the pump through the switch like some modern versions.]
Having owned 5 of them through the years and a couple Monza and a "slightly" modified Starfire, The only one that ever had problems was a first run 71 with the original block. Once they started the Durabilt engines they were not a bad little car. For an Opel Kadet based vehicle. The real problem was the total lack of rust proofing and sealers. You could just about hear them rot....

Yep they had a carb BUT an electric pump. They used the O/P switch to turn off the light and power the pump. That was a carry over from the Opel Kadet design they were based on.
The astute observer will note that the posed inquiry related solely to "one specific model car" and the above response didn't explicitly delineate so much as a single example. ;^)
I'm not an expert in this area but, except for tractors and Model Ts, most vehicles such as the Vega have a fuel tank well below the carburetor so a fuel pump is necessary for engine operation. Did I miss something?
Yes, the Trabant! They mount the fuel tank directly above the engine so that no fuel pump is needed.
This is why the Trabant is the most reliable car in the world. It has no radiator, no water pump, no fuel pump, no valves, valve train, or timing belt. There's nothing to go wrong except for catching fire a lot.

danielle, i'm sorry you decided to leave san francisco. but somehow, we all seem to manage without you. it's like you were never here.
i never really understood this on carburetted cars. with a mechanical pump, if you crash and the motor stops, you stop pumping gas. with electric pumps and the engine stops, it just keeps on pumping, potentially into a nice toasty engine compartment. unless you introduce more complexity/potential unreliability in the form of an inertial switch.
The ENTIRE line of GM S series from 1989 - end of production. That would be the S-10, T-10, S-15, T-15, Blazer, Jimmy, Bravada That specific enough?
Isn't my newly established leg-humper precisely reminiscent of the never having anything of actual value to contribute ignored child, flailing his arms and screaming "PAY ATTENTION TO ME!".
Is it the definition of the word car, as opposed to truck (or, by another term, sport utility vehicle), or the ability to parse the english language in general, that has you so flummoxed?
Or even easier, power the fuel pump off a Tachometric relay running off the coil.
Cheers Dre
even simpler yet! not.
personally, i'm all for electronic fuel injection where the computer runs the show. the computer is "complex", but is solid state, has a very low failure rate, and can be relied on much more than any electro-mechanical device.
"dear danielle, my 'friend' thinks she might be fat and has no [other] friends because she blames them for her being ugly. what should she do? signed: still living in mom's basement."
danielle responds: "dear mom's basement, your 'friend' is simply being dishonest if she's blaming others for her own faults. the first step to recovery is to end the denial, get out of that basement, and look forward to the onset of puberty with the hope that with it, the personality carbuncles currently afflicting them might pass."
Specific enough.
