IF you have the EBL upgrade, all that is required to pulse the injectors is pulses from the distributor. I asked this question to BobR of DynamicEFI while remotely troubleshooting another GMCer's issues and this was his response:

> Can you advise me the input signal requirements that must be met for the EBL to start firing the injectors during startup.

>>All that is required is the distributor reference pulses (DRPs). The crank signal is not required, that just lets the ECM know when to test the fuel pump relay.
