Are you confident you havent got the HT leads on the wrong way round? That would explain the white smoke...
Yes, they are correct.
Pump runs only in 2 ways:
Linking pins 19 and 28 on the ECU multiplug or direct 12v from the battery with a temporary cable.
Problem is that I don't have another ecu to test with. Was promissed one here from a Portuguese guy but hasn't said anything till today.
