Hello John. The Montana/Venture vans have a problem with the fuel gauge sending units in the early 2000's. The only cure is to drop the fuel tank, remove the sending unit and replace it. The fuel gauge sending unit is available separately from the fuel pump. Thank you for using FixYa. KL
You have a bad fuel level sensor.The fuel tank needs to come out and the sensor replaced.You don`t have to replace the pump assembly.You can get the level sensor separate.I`m not sure if the parts stores have it but I know the dealerships do.Hope this helps.Good luck.
The fuel level sensor is bad. The tank will have to be taken down to replace the level sensor. There is little fingers on the resistor that wear down and loose contact causing the gage to read incorrectly.
Most likely it a bad fuel level sensor on you fuel pump. You will have to replace the fuel pump as that is the only way to replace the sensor for you fuel gauge. The sensor is built into the fuel pump. The contacts on the sensor become corroded over time and cause the sensor to malfunction causing your fuel gauge to read full all the time. I have a 2001 Montana extended version that had the same problem. In order to know when I needed to fill the tank, I would completely fill it each time I put fuel in and reset my trip odometer. I would go 400 miles on the tank before I would refuel until we were able to replace the fuel pump.
When gauge is pegged at full, usually means a bad ground. Check wires at fuel tank, wiggle around, maybe one came off. The bad news is it is hard to get to without removing the tank. Sometimes you can reach arm in and get to them. Also check body ground at read of van.
replace fuel pump/Fuel gage sending unit (All in one) also wire pigtail to asmbly Pontiac Montana's are prone to wire falures and shorts $300+ if done in drive way alot more if you have a shop do it!
P.S. REPLACE ASMBLY WITH AS LITTLE FUEL IN TANK AS YOU CAN...!
