Injectors not working So my wife's 97 vert 3800 fuel pump went out. I bought a new one installed it and have 47 psi at the rails. Still won't start unless i spray ether in it. Vats seems to be working fine. What do I need to do?

Do you have spark?
As crazy as this sounds, I recently chased a similar problem with my car not starting. Engine would spin just fine, but I had no fuel and no spark. After replacing the cam sensor, crank sensor, and trying all sorts of other things, I realized that my battery was dying. It had plenty of juice to spin the motor, but not enough to fire the injectors or coils...
I banged my head on the wall for a while after that, but was glad to solve the problem. For kicks, put a charger on your battery, or a set of cables on another car, and see if it helps.
Good luck.

I do have spark, i let my silverado charge the battery while I tried starting it but no luck. Luckily for me my wife has a new chevy sonic for daily use. However, i still need to get her baby fixed. I know the injectors work and are clean of blockage. They just aren't getting power. I'm baffled
