Just installed another stock redtop ecu and stock sr maf. Swapped in a different walbro 255 inline pump that we know works to be certain we are getting enough fuel pressure. Fuel pump sounds different like maybe more fuel flow but car still won't start. We are getting code 34, knock. Will the car still start with code 34? Is it possible to actually have knock when the car is only turning over not starting? Is it more likely the sensor is bad? If I am actually getting knock would it damage the engine at idle? Motor is freshly rebuilt and I obviously want to avoid damage. Thanks,
JKP
