Lost power to injectors?

I have a 57 Chevy with a 05 lq9 motor. Car is not driveable but would start and run in the shop. It now will not start. I have checked the fuel pressure, 58 lbs. it will try to start on a shot of ether, so I assume I have spark. It seems like the the injectors have lost power. I have checked everything I know how. Any suggestions?
Thanks, Ron

Get a NOID light to check to see if the Injector are getting a pulse while cranking. You just unplug the connector from the Injector and insert the NOID light into the connector.

You can google or search online to find out more about them. but here is a post on LS1Tech
