Express 1500

Erratic Fuel Gauge Operation on Chevrolet Express 1500

Problem Description and Possible Solution

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.

Bought my friends 2000 Chevy 1500 express conversion van with 6,000 miles in 2011. Fuel pump went without warning on trip to Florida. Had about 18,000 miles on it. Left me stranded with family with $1200 repair.
I ran out of gas two weeks ago. I thought I had forgotten to fill up. Ran out of gas last weekend again on a road trip and fuel gauge showed 3/4 tank.I filled tank and gauge moved to full. Now its moving from 1/2 to 3/4 as I drive. Fuel pump still working but I have to replace sending unit attached to fuel pump.I have 37000 miles on the vehicle now.
I think I had ran my gas to low after my gas light went on. Would that cause my fuel sensor to go out? So now when I put gas in, the fuel gauge fluctuates up and down and I never know how much fuel I have.
Gas gauge needle swings from full to empty. Also, stalling and not starting. Shop diagnosed problem; fuel pump. Replaced it and problem solved. $750.
Fuel level reading behaved very erratically. Would read empty most of the time, but would occasionally jump to non-zero level. Replaced the fuel pump assembly in the gas tank and the gauge now registers the correct fuel level.
Have never fixed it, can not afford repair. Every time I fill up I see my trip meter to 0 then fill up again before I reach 300 miles
When my tank is completely full, the gauge only reads 3/4 full. I don't know where empty is. I've ran the needle down to 1/8 of a tank and still had 10 gallons left as a guess.
Have not fixed this issue. We just know when the van is parked on an incline the gauge shows less gas than we have. And when it's parked facing downhill it will show more gas than we really have.
After filling the tank, the fuel gauge drifted around 1/2 full. It would work for the last half of the tank. About one month later, it went to empty and has stayed there. I use the trip indicator as my gas gauge.
Gas gauge fluctuates from full to empty. I've ran out of gas several times not knowing how much is in the van. Gas gauge won't go past half a tank.
