1991 honda civic dx main relay failed one of 3 continuity tests how to fix it
I have a 1991 Honda Civic Dx that will crank but won't start. Even after hooking up booster battery to it and getting well over 13 volts, spraying starting fluid, and checking fuses which turn out to be good, I just simply hear it crank but no fire. However, when I placed my hand on main relay when attempting to start it, I felt no clicking. As I understand, you're supposed to feel a click when turning key over and starting it. So I simply took it out to test it according to these instructions:
In the first test, I heard clicking as soon as I hooked mini booster cables to terminals 4 and 8 of the main relay, and I got a resistance reading of 0 when using a multimeter to test terminals 5 and 7.
In the second test, I didn't hear any clicking after hooking up booster cables to terminals 5 and 2, and I got a resistance reading of 1 when I tested terminals 1 and 3.
In the third test, I heard clicking as soon as I hooked booster cables to terminals 3 and 8, and I got a resistnace reading of 0 when I tested terminals 5 and 7.
According to many youtube videos and other internet posts, main relays could be desoldered and then resoldered to make them work again. According to pictures below (if you need better pictures, let me know), could my main relay be fixed by getting desoldered and then soldered again? If so, which points should be soldered and then resoldered?
All answers, tip, advice, and help would be much appreciated.

I have a 1991 honda civic dx that cranks but won't start even after trying starting fluid on it, hooking up booster battery to it and getting well over 13 volts, and checking all fuses that turn out good. However, when I placed hand on main relay when turning key over and attempting to start it, I didn't feel any clicks like I believe that you're supposed to when starting it. So I took it out and decided to test with another battery and a multimeter following these instructions:
I heard clicking sounds after hooking up mini booster cables from another car battery to terminals 4 and 8 of main relay. I then tested resitance with a multimeter to terminals 5 and 7 and got a reading of 0.
I heard NO clicking sounds after hooking up booster cables to terminals 5 and 2 of main relay. I then tested resitance with a multimeter to terminals 1 and 3 and got a reading of 0.
Just like the first test, I heard clicking sounds after hooking up booster cables from another car battery to terminals 4 and 8. I then tested resitance with a multimeter to terminals 5 and 7 and got a reading of 0 just like the first test.
What does it mean when there are no clicking sounds as soon as I hook up mini booster cables to terminals 5 and 2 of main relay? As i understand, main relays often could be fixed by desoldering and then soldering again. According to pictures below (let me know if you need me to take better pictures), which contact points of main relay curcuit board should I desolder and then solder again?
Let me know if you need anymore info. All answers, tips, help, and advice would be much appreciated.
