update:
swapped in a new odyssey pc1200 battery, still no closer to getting it started
i have voltage at the injector plugs although this is different to injector pulse which i cant hear during cranking with screwdriver
if so, that would point the finger at the CAS right?
when measuring voltage at ignitor, do i have to earth out the E during cranking in order to get voltage reading?
also have re-plugged the ECU and relays near it, yet to test voltages at the pins
btw, car started briefly with the new battery for bout a minute, idled normally, could hear the injectors being their noisy normal self, then on its own it splutter few times and died
