fuel pump not priming with hondata but will with factory ecu

so ive been having some intermittent problems lately....
fuel pump sometimes wouldnt prime straight away, might have to wait 10,20,30 seconds, sometimes would prime instantly.
so i decided i would try work out whats going on tonight, because i waited about 5 mins and the pump still wouldnt prime, so i checked all my earths, (inc one on the thermostat)
tried to hard wire the fuel pump, fuel pump primes but car still wont start. assuming that the ecu isnt giving an injector signal.
so lastly i put the factory ecu back in, and bam fuel pump primes and car starts.
WTF? is the ecu dead? can it be repaired? what should i do?
