I own a 2002 Chevy Cavalier with 131,800 miles on it. I had the fuel pump replaced 2 weeks ago and ever since then, I have noticed that the car seems to be burning almost twice as much fuel. I refilled the...

There most likely isn't a problem. The fuel gauge works off of a reisistor board that's mounted on the fuel pump assembly. There is a arm with a float attached to one end. On the other end there are needles that touch the resistor board. The float level changes where the needles touch the risistor board and that changes your fuel gauge. Not all resistor boards read exactly the same, especially if an AC Delco pump wasn't used. The gauge is just reading off a little bit compared to your original one. Try filling up, resetting your trip meter and then driving a good bit. When you fill up the next time figure your gas mileage by dividing the miles you went by how many gallons you used. I bet your still getting around the same gas mileage.

All your gauges are working. The gas gauge Is also working. When you fill it, you will fill over the limit the fuel level switch will go by a couple of gallons. So the gauge will not drop for a few miles. until you use up the excess fuel

weird...first thing to do is get a scanner hooked up to see what caused the check engine light-free, at pretty much any retail auto parts operation-i wouldn't get overly concerned with the gas gauge right now, teh code that tripped the check engine light might explain that problem.

My 1996 Pontiac Grand Am GT stick shift vehicle keeps dying. It will shake when the gauge gets to the 1 RPM spot and continue shaking for a little bit and then just die. I have replaced the oil but perhaps...

Wrong, it couldn't be the battery because the battery is basically used to keep track of the time and make sure your car starts, after it does the battery basically charges and runs like the radio etc. The fuel filter would be more likely, but my money's on the fuel pump itself. You might also have an engine coil firing out of order, which would cause the shaking and an occasional **** from the car.

-Get a tune up.
-Get a machine hooked up to your car by a mechanic (full systems check)
-Check the transmission fluid.
-Tell the mechanic that it's probably the fuel pump. The fuel pump starts going bad, and then your gas gauge starts fluctuating, and your engine starts struggling to get to higher RPM's because it can't **** fuel out of your tank fast enough.

All in all to get this baby back on the road at full force could run you 200 to around 500 dollars. Then depending on the mechanic the labor is more.

Tune up (100 bucks) transmission fluid change(20-50 bucks) Full systems check (50-80 bucks) fuel pump(150 bucks) then the labor for everything would be anywhere between 150-300.

Hope it helps.

2002 Jeep Overland 8Cy 4.7L check gauge light

If the engine isn´t making any abnormal mechanical noises, then I would expect the oil pressure sending unit at fault.
If however the engine does make more or abnormal mechanical noises, it could be a too low oil pressure and this should be addressed immediately.

My gas guage is not accurate, the needle seems to jump around while driving. I ran out of gas at 1/4 tank the other day. What could the problem be on a 87 iroc z?

GasparMacari is 100% on target. I had the same problem with my IROC. Seems that the sulphur in the gas errodes the contacts on the gas gauge sensor in the fuel tank. I know of people that have tried gasoline additives to clean the corrosion but I would give it a 50/50 chance of working. You gotta drop the tank to get at the fuel pump/sensor assembly. You are looking at some big bucks and it is NOT a do-it-yourself project. One spark and BOOM no more Camaro... or YOU... I'd suggest setting or re-setting your odometer trip indicator every time you fill up. Keep track of the miles driven .vs your MPG and you can figure out when it is time to fill 'er up again. That's what I did until I traded it off.

My 1999 Oldsmobile Alero Gas gauge and fuel system

well # 1 the full gauge when empty is a sign that your fuel pump is bad and that needs to be replaced the part about spitting the gas back out is probrobly a clog between the fuel door and the tank itself or their might be a vapor lock door that might be stuck shut so fuel cant get in im not 100%sure about that but im 100%sure that the fuel guage is the fuel pump being dead.
