MPI relay clicks and car cuts out, with fuel pump directly wired to the battery the car runs great, how can I test the 1g (92) MPI relay to make sure the relay is good?

Today, for the second time mine also cut on and off over and over again.
The similarity is that it's cold raining and the car on first startup will cut off after the mpi relay clicks.
Then i'll restart the car and it'll keep clicking on and off, while the car fights to stay alive.
I then have to reset everything in my ecmlink, because it deletes it for some reason, if i can get the car to keep running for 5 minutes, it may not ever happen again for 3 months, untill it's cold and raininy outside.
I'n my case it seems to be a short somewhere, causing it to ground out, but if it gets hot enough to remove the water, wherever it may be, the short goes away, until the next time.
or it's something inside the ecu going bad. I just had ecmlink replace my mpi relay output less than 2 months ago.
Ive looked at the link many times curious as to how to apply power to watch the coils close? tried applying power to connector 10 and all it did was spark...

this is pretty much how mine is finally solved a boost issue took it out for a drive ran perfect pulled hard everything i was so happy, parked it, tried starting it started perfect, then next morning starts mpi relay clicks car dies so mad but its done this in the past as well then goes away sometimes, id like to fix it for good and be done with it, I just had the caps redone on my ecu about a month or two ago so im pretty positive its nothing to do with the ecu. Ive replaced the mpi relay a year or two ago but i guess I wanna test it this time before blowing 75 bucks at the dealership again
