X485 wont start

I stopped to refuel my X485 and now it wont start. I do not hear the fuel pump priming when turning on the key.

There's a fuse for the in tank electric fuel pump. Not exactly sure but it's probably located behind the right side panel. I just had the same problem with my 455 and also on a 425. Sometimes the plugs get worn out or dirty. Most likely that's all it is. Hope this helps you out. I'll check back.

It could be bad connections going to the fuel pump. I have thought several times that I needed a new fuel pump with the same symptoms that you note. But so far every time I have managed to get the thing pumping. This is not real easy to check with a voltmeter.
Mine is 445 but the setup looks similar. You also have supply + return voltage in these wires for the fuel sender.
On mine when the switch is turned on the fuel pump is energized for about 4 seconds then is turned back off until it's cranked.
This complete assembly is expensive so hope you don't need it.
I am told that the actual fuel pumps rarely fail. Some gets replaced when the problem was actually the wiring.
It may also have a relay to turn the pump on.

I have voltage all the way thru to the fuel pump it self. New one is to arrive today. Thanks all for the info.

Installed the new Fuel Pump Sender unit and it started right up.

Too bad, you could have used this as an excuse to go get a new X7!
