92 240 wagon m47 5 speed starts and idles but stalls upon acceleration

[mysoonergirl]

hello-
I have a 1992 volvo 240 wagon 5 speed manual. I have not been driving a lot since covid closures so she doesnt drive as much as usual, however I had the follow issue this evening. I did drive yesterday and did feel that at times she was losing power

She starts fine and will stay in an idle with no issue however when I press the accelerator- there is no power transferred to the engine (even when peddle is depressed all the way to the floor) and the engine stalls out.
I can put the car in gear and take my foot off of the clutch and the car will remain in idle as well, it isnt until I try to depress the gas pedal that she stalls
No warning lights on dash to signify an issue
I have checked and replaced the fuses for both fuel pumps (although main pump fuse has a history of overheating and melting)
I hear the fuel pump turn on
Throttle linkage appears intact and moves appropriately when maneuvered.
o2 sensor appears normal

Any help is appreciated

When was the fuel filter(s) replaced? There should be a large filter near fuel tank and another in the fuel tank. If either or both filters are clogged, the engine will starve for fuel above idle. Old fuel in the tank will increase the likely plugging of filters. Fuel pump is working or the engine would not start and idle.
Can you check fuel pressure at the fuel injector fuel pipe? Can you check the fuel filter condition by removing and pouring fuel out the inlet to check for condition of fuel in the filter?
