It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.Google+

Fuel gauge says there is 1/4 tank of fuel left, but it won't start. It does start if I add fuel to tank.

My fuel level gauge has completely stopped working...at first was sporadic (but always wrong) and now it just points straight down. It has not been fixed.

When the tank is full, the gage will read empty, and then will start working when the fuel level comes down - but after about half a tank, it becomes erratic.
fuel gauge no longer goes all the way to "Full" - it stops between 3/4 and full.

fuel gauge occasionally but rarely reads the correct level, usually pegs all the way empty. we use the trip to keep track, @300mi, fill up. when towing, @220mi.

My fuel gauge begin acting erratically after a few months after buying the vehicle, running out of gas & the gauge reads that I had a 1/4 tank. Had the vehicle towed & did my own investigation since I'm very mechanically incline with diesel trucks & cars. Now to find out after shooting starting fluid in the intake & it started up but shut down after a couple of seconds. Put about $10 of gas in the tank & it started right up! Yay! Now I know it's a problem with the sending unit in the tank which is connected to the fuel pump, just to find out it's all one unit & best to replace the whole fuel pump to get the proper reading on the dash to prevent this to happen again even tho the fuel pump is working fine.. :( very expensive part $300-$400 if you do it yourself, so if u have this problem then that's what it is!
