Question about 2007 Mercury Mountaineer
I think its a fuel problem .when I disconnected the fuel reset switch it starts then dies
Fuel pump relay, turning the ignition on runs the fuel pump for about two seconds to pressure the fuel rail to start, then the fuel pump relay takes over once engine is started, it relies on a signal from the ignition or ECU (to say keep running). Either the relay has gone down or the relay has lost the signal. Don't bypass the relay, it's a safety feature, to stop the fuel pump if a fuel line ruptures.
