"Crank-but-no-start"/"loss of throttle" turned into "Barely Even Cranks problem" (1 Viewer)

Update (really just to close this thread out):

Ordered this fuel pump assembly, installed it today after coming back from the holidays and the car started right up, no hesitation.

Thanks everyone for the help!

Fairly new user (came across the site when I had to replace the barrel ignition rod and found some helpful posts/links) and I am at my wits' end.

My problem seems to have morphed from the "intermittent crank-but-won't-start/loss of throttle" problem into a "car has trouble even cranking at this point". Below is what I'm dealing with - any help appreciated.

History of problem:

• (2023-11-06): (Likely unrelated but worth mentioning) Filled up with “suspiciously inexpensive” gas.
• (2023-11-06): Car started pulling out of gas station; no problems
• (2023-11-06): Next startup, not 20 min later, started fine, kinda “chugged” for a minute below normal RPMs (just sounded off in general) and engine stopped
• (2023-11-06): Wouldn’t restart —> towed to shop —> shop was able to start with gas pedal floored
• (2023-11-07): Took car from shop, everything seemed fine. Life is good.
• (2023-11-11): Driving a few days later, lost the throttle. Pulled to side of road, started up immediately/on first try, continued day.
• (roughly 2023-11-15): Some days later, car cranked but wouldn’t start at home. Stayed like that for a few days.
• CEL is on at this point.
• (2023-11-16): Pulled out/checked EFI and ECU fuse (both looked good), put back in and the car starts no problem.
• (2023-11-16): Car appears to be idling perfectly at ~1000 rpms, take a little drive around the neighborhood with not problems.
• (2023-11-16): Turn off car and try to start again. Doesn't start. Try the "pull out and put back in EFI/ECU fuses" move that worked previously and
• car still doesn't start and hasn't started since.
• ( 2023-11-30 ): Tried using starter fluid, sounded like it really wanted to turn over but still didn't start.
• ( 2023-11-30 ): Car now has trouble cranking, much less starting.

The current status of things/what I've checked:

• with key in On position:
  • security light is **not** on
  • CEL is on, although no codes are coming up on this scanner I bought.
• Cleaned the throttle body.
• Checked APPS - looks good.
• Checked Fuel Pump & Sender Gauge Connector - looks good.

Ive been chasing an interminient loss of throttle for a while. I resolved it with a new fuel pump relay, previous owner installed a knock off 30amp relay
