Fuel Gauge Problem

[MENTION=61846]High_Order1[/MENTION]: It seemed to resolve itself somehow. It's been working flawlessly for the past maybe 6 months or so without any issues, so I don't know what's causing it (or what caused it). I didn't do anymore troubleshooting because it literally has not done the drop to E thing at all anymore. I'm not sure what the cause could've been, but it seems to be behaving itself for the time being so I figured I'd just let the sleeping dog lie haha

Before when it used to happen, it wouldn't take 10 minutes though. It would basically seem to take a different amount of time each time. Like I'd fill it up with gas and then start the car, it'd be fine. As soon as I put it in Drive and start moving, it'd just drop down constantly. Or like it'd be good after i start it up after work, and then after driving maybe 1/2 mile or so, it'd just drop to E randomly.

Maybe one thing to note is that at first, it would drop to E and then stay there until I restarted the engine. Towards the end (right before it started behaving), if it'd drop to E, it would basically fix itself. Like I'd start moving and it'd drop to E; then after a few minutes of driving, it would go from E to the correct fuel level again and stay there showing the correct levels. And I literally just did a 400 mile trip yesterday from Buffalo, NY back to NYC and the whole time, it was behaving. It didn't drop to E at all during the trip.

Hi there I hope this helps but most likely the issues going to be with the fuel sending unit connection. I've had the same problem multiple times with multiple fuel pumps and after a year or so it will happen again. Ford tends to use very small gauge wires and very and reliable connection points and they tend to short out the sending unit. best bet is to use a new fuel pump with a little bit of dielectric grease in the connection.
