Nobody has asked yet but is the car all stock? No headlight, taillight, HU etc swaps?
The relay is #45 in the attached diagram. There are also a couple of fuses. #21 under hood and #14 under dash. If it is so intermittent it could be the relay.

Back with another update. I’m planning on taking both the starter and battery to the store tomorrow to check if they’re good. Car is completely stock, no modifications.
I checked the fuses and none were popped. Swapped #14 for a horn fuse with the same voltage, and it started! Turned it off, and then it didn’t want to start again. Swapped the fuse again (other horn fuse), it starts! Turn the car off, it doesn’t start AGAIN. Swapped the fuse for a third time with another good fuse (AC)…it starts. I drive it around after draining the transmission fluid a bit, that fixed the sluggishness. I park the car, turn it off…it doesn’t turn on AGAIN. I can hear a clicking around the location of the fuse box under the dash so I’m thinking that at least works. Swapped the relay with the dimmer relay and nothing. Tested the original starter relay (only the two vertical pegs, as I don’t have the tools to change them and test the horizontal ones for continuity) using Ohms, and the reading dropped to 0 or some lower numbers, fluctuating.
Lastly I tested the starter wire like explained earlier using the chassis as a ground. Absolutely no reading when turning over the car. I did that before swapping all the fuses around, before I got the car running. Every time it didn’t want to turn back on I tested it and found no reading.
Clutch switch, starter wiring harness, or relay? Take a guess lol or maybe something worse?
Here’s a photo of the starter #14 fuse before swapping it for the horn fuse for the first time.
