Long story short , bought the car y7 - auto blown up
swapped in y8 and manual trans
trying to get car started , no fuel prime or crank, main relay doesn’t click
all three fuses feeding main relay good and sending power at correct times, fuel pump works when adding power
relay ground has 11.5v
adding ground makes relay click but still no fuel prime or crank
could relay have internal short to power on ground leg ?
Vehicle has aftermarket harness and ecu at this point
