Do you still have fuel pressure when it quits? Just lose injector signal? Is the PCM spitting any codes??

When the engine is running, they should always have power. If it isn't running, only for about three seconds after you turn the key. PCM needs to see the engine turning to power them up. Since it will run on starting fluid, or whatever, seems the coils are still getting power.

Injectors are fired in pairs. So, two cylinders failing, I could see the pcm being responsible for, but ALL cylinders? Gotta be a sensor or relay out of whack.
