Default runs with starter fluid. No injector pulse

So I'm helping my brother with his 1994 firebird LY6 conversion. We're running factory electronics, including the drive by wire.

So everything seems to be wired correctly. The only error codes we are throwing are for emissions related stuff.

For what ever reason, the ecu is not engaging the injectors? There's 12v on the pink wire of course, but no ground from the ecu to engage?

We have disabled the anti-theft crap, but still no activity at the injectors.

Any ideas on what might stop the ecu from firing the injectors?

Were the injectors new or used? If used they could have gummed up.

Got the motor sputtering a little bit. Now just got to work on running continuously.

It runs. It's flawless.

Ly6 in a 1994 firebird on factory ly6 electronics. It might be the first?
