There should always be power at the injectors as long as the fuel pump is on. The fuel injection ECU provides a ground to the injectors to turn them on.
You most likely have a bad fuel injection ECU. This is a very common failure on 88,89 and 90 SAABs.

Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

I had same problem in my 90 deville. Drove myself crazy, I replaced the sending unit in the tank with a new fuel pump. I also had to replace the fuel pressure regulator, which sits behind the rail system. It worked for me.
