Why does my 6.4L Powerstroke not get MPGS?
Despite the impressive 6.4L Powerstroke specs and features that make these engines a powerhouse, they lack substantially when it comes to fuel efficiency. The major reason for the 6.4’s lack of mpgs is none other than the new diesel particulate filter. Active regeneration uses diesel to increase EGTs and clean the dpf.

What should I do if my gas gauge is not working?
Note that some self-test steps may stop the gas gauge at 1/4, 1/2, and 3/4, as well. Fuel sender test. The fuel sender test should be conducted when the tank is lower than HALF, to prevent fuel splashing. Start by making sure the plug is clean, dry, and free of corrosion. Make sure the pins are straight and that the connector is fully seated.
How does the gas gauge work in a Ford?
As your gas tank is drained of fuel, the float drops and an electrical current is sent to the gauge to tell the driver what’s going on with the supply. When the fuel level changes, the current also changes — higher currents mean the tank is full and lower currents mean the tank is moving towards empty.

What should I do if my fuel gauge is stuck?
If the gauge gives you a full reading, the sending unit is faulty and should be replaced. Verify that all of the wiring is securely connected to the back of the fuel gauge, which will require you to remove the dashboard to gain access to the instrument cluster.
Why is the fuel gauge on my Ford PowerStroke not working?
When I bought it the fuel wasn’t working (stuck on E with low fuel light illuminated) they said Ford had diagnosed it being a bad sending unit and parts were already ordered so I went ahead and bought it. Dumb idea I know. 5 days later 2 fuel injectors went out and the only way they would fix it is if I did the sending unit myself.
What do I do if my gas gauge is not working?
In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.
How do you test a stuck fuel tank?
Test the grounding wire on the fuel tank’s sending unit, which is attached to your vehicle’s fuel tank. To do so, attach the negative jumper cable to the car’s frame, and the positive jumper cable to the grounding terminal of the sending unit.
Why does my gas gauge keep pegging full?
The gas gauge might interpret voltage feedback from a dead sender as FULL or EMPTY, consequently pegging the gauge no matter the actual fuel level. Circuit Problems can cause the gas gauge to stop functioning normally.

What should fuel gauge resistance be at half full?
Start at the fuel tank. Using an Ohmeter (or digital VOM): check the resistace of the sender (to ground), with the wire disconnected. Make sure it’s not shorted or open. The resistance should be between the limits stated above (A half-full tank should be around 80-85 ohms).
What does a zero ohm fuel gauge mean?
The reading should now be zero ohms (or close to it: Less than 1 ohm). This will prove that the wire is not open. These tests will determine whether the wiring is good, shorted, or open, and whether the sender is good, shorted, or open. If all tests come out good, then you most likely have a bad gauge.
