Default injectors not pulsing, have spark

Just dropped an LS6 in a Porshe 944.

I have spark, no injector pulse. If I spray starting fluid it fires.

There is power to both sides of the injector, niether side ever goes to ground. Plugs are sparking, does this indicate the CPS is OK?

I have a standalone Delphi so there are no VATS issues. I checked all the simple stuff, power, grounds, batt charge.

Ideas?

I have the same problem, LS1 in a 91 RX-7. Also only runs on ether.
Hooked a NOID light to an injector on each side.
Flashes twice and then stops during cranking.

Any insight on this?

I'm having the same problem. Put an LS1 into a 944 turbo. I pulled the rail and injectors, and when I crank it, looks like they puff one shot of fuel each, and then nothing. Any ideas?
