Have tried removing one at a time, no change. When rail is removed, plenty of fuel through port. Will run with fluid. Have already replaced: ECM, mass air, plugs/wires, fuel pump, throttle position sensor. Fuses all good unless there is one inline I don't know about. Mechanic friends are stumped and wife is panicking. Any suggestions?

Check fuel pressure with a gauge should be 41-47 psi with key on only. If injector is bad it would miss. If there is no signal pump will not run check MAP sensor for a soft hose or being bad as they won't run if that is bad check inline fuse by starter for pump.
