Default main relay

Hey today i was testing coils on my distributor. then after testing the 2nd coil i had. i tried to turn on the car and it would not start. starter cranking etc. i had enough battery juice i checked with multimeter.

and i did not hear my fuel pump prime or the main relay click. After about 30 minutes went back. I tapped my main relay few times, heard it click and the car turned on.

main relay likely cause? or could it be a fuel pump gone bad?

Unless the pump is aftermarket, the pump is probably fine. Honda pumps rarely fail. Main relays of that style fail regularly.
