Uh, there will be voltage there if the fans run and the fuel pump as well. Need to be checking more like the relay coil activating circuit as the relay is supposed to be powered up and grounded only for like 2 seconds on fuel pump meaning it's grounded when shouldn't be. Same with fans, they should not be grounded at least on the relay coil circuit. The relays clicking on/off could be a partial voltage getting to relay coil that is not enough to hold relay fully on, the spring then overrides that to cycle on/off rapidly. Or a partial ground. If new relays do the same then an indicator the relay coil circuit is flawed with either power up or ground, probably the ground side.
I see that battery has been swapped but is the one being used now a KNOWN GOOD one that has passed battery load testing? Seen people go crazy while assuming battery was good, when it wasn't, a low battery on modern EFI cars will make some pretty crazy effects.
the battery was swapped out of yet another ford probe that i drive daily so both batteries are good.
for the relays, i believe the pcm controls the grounds (pins 45 and 80 are the grounds at the pcm) when i ground those pins at the pcm harness it stops the chattering of the relays but still wont start. ive checked the pcm grounds and theyre good.
