What ecu, wiring and throttle body are you running? MSV70 has a injector relay that is powered by the CAS, MSV80 switched to being from the main relay. A mismatch of parts could be causing your issues.

MSV80.1, Stock E92 harness with a Redline motorsport adapter harness specifically for N52N MSV80 and E30 that does use a relay.

So you are using an msv80.1 dme, do you know if it is from an e83 or a n51 e9x? Do you know what year e92 engine harness & if it was n51 or n52? You should have power to the orange wires at all of the fuel injecors with the key in the run position. The dme will ground them to fire. So first check will be seeing if you are getting power to the injecors, check from pin 1 of the injector harness to chassis ground, not across the 2 pins. That wire would be powered by the main relay in the junction box behind the glove box in an e9x, I'm not sure how the redline harness powers it.
