I just had this problem with my 2002 Pontiac Montana. It did the same thing for several weeks before finaly the fuel pump went out. When I replaced it, I saw that the gauge on the end of the "handle" on the old fuel pump that reports how much gas you have looked twisted and bent (not sure how that happens). This was basically the first sign that the fuel pump was going out. And when the fuel pump finally went out, the van was sputtering like there was no gas in it, and then cut off. So you dont get stuck on the side of the road like I did, get your fuel pump checked out.

My gas gauge goes from empty to full within 5 seconds, and it will show low gas when there is half tank or more..


Replace the sending unit in the tank. You don't have to replace the whole pump assembly, You can buy just the gauge sender from the dealer.

Fuel Gauge Stuck on Full 98 Pontiac Montana


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.

Temp gauge and gas gauge not working


I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck

1989 mazda 626 turbo window washer pumps


well the pump for the washer solvent is probably fried (unless there is no solvent in the resovoir). and on the gas gauge the way that works is there is a little float handle that goes up and down with the gas. when you put gas in this little float floats on top of the gas and this is how your car knows how much gas you have it sounds like it is getting stuck and will probably need to be replaced
