Default Re: Vue stopped working. Blinking security light.

And still no SES light? Next step can be fuel pressure testing. When the igition key is turned ON there will be a faint hum/hiss of the fuel pump running (try listening for it) for 2-3 seconds then shutting off (for safety); locate the fuel rail's test valve, remove the large black plastic cap (this schrader valve resembles a tire valve), cover the valve loosely with a rag while depressing the valve stem expecting a healthy spray of fuel. No fuel or a dribble means a fuel issue; fuse, pump relay, wiring, ground.

REWARD EXCELLENCE!
