Question about 2000 Oldsmobile Silhouette

1 Answer

Was driving, car shut down, acted as if running out of gas, has full tank, been sitting a while now, replaced fuel pump relay, fuel filter, new battery, will crank, just not turn over,can hear the pump turn on when the key turns on but it just won't turn over do you think we need to replace the pump? can a catalytic converter cause this problem? had a guy check the system before any of this happened said that it was running lean? he had it for a day and said he fixed it, maybe he did maybe he didn't don't know.

Assuming no service engine light on? If so begin there. Otherwise it sounds like fuel pump could be bad, but you'll need to install a pressure gauge to verify - that's the only way to be certain. Compare pressure with spec. for your vehicle. You'll likely hear the pump as most fuel pumps continue to run but just don't produce the pressure necessary for operation. In fact, due to improper fuel filter service, many pumps actually get louder when bad. Before spending money on a pump, borrow a gauge and verify pressures. Many auto parts stores now days (such as O'Rilley) loan tools (with deposit) for testing and repair.

Hello I just bought a 92 accord Lx 5 speed. first i found out my fuel gauge gives me wrong reading it says is 1/4 full when is empty. my second problem is when I'm around 1/4 tank full the car shuts off...


I dont know why car shuts off when the tank is 1/4 full. Try replacing fuel filter first then maybe fuel pump. I think you probably have a stuck fuel sending unit. Here is a video of the location of the fuel sending unit.

Acts like it has no gas


The electric fuel pump in this truck is inside the fuel tank, the fuel that the pump sits in provides cooling and lubrication for the fuel pump, when you run out of gas it is like running the engine out of oil, it damages the pump,You will need to remove the fuel tank and replace the fuel pump.

2001 Durango acts like the gas tank is full during filling cutting off the pump. The only way to fill tank is to pump gas really slow


Chrysler and Dodge have a fuel vapor filter that allows air out of the gas tank but filters the harmful fumes. Usually the problem happens from topping off your gas after the gas pump stops due to the automatic shut off and then putting more gas in the tank (to make the bill an even $50. or to the next $5 increment, or pumping more in just because it fits). Anyway the filter gets saturated with gas, is not able to breath, and causes a vacuum in the tank. Because of this, the anti-siphon ball is not able to float around and sits at the opening of the fuel fill tube and won't allow any more gas to be put in (acts like the car is full). If you pump super duper slow like put a nickel to hold the gas pump handle, it will trickle in without a problem, but it takes forever! Solution, get the filter replaced and don't over fill the tank.

Truck acts like it is running out of gas? Replaced fuel filter. Ran fine for awhile but now still acts like it is starving for fuel.


my '93 f-250 (4.9L) stopped running while driving, now it acts like it isn't getting any fuel. Tried switching tanks, but still does the same. What would be the problem.

Not getting gas from the tank to the engine


Then either the fuel pump has failed, fuel filter is clogged, fuel pump relay is bad, or the fuel pump fuse is blown. Sit in the car in a very quite area or with someone listening at the fuel fill area with the cap removed and turn on the ignition without starting the engine. The fuel pump should come on for a few seconds and then shut down. If it does not then check the fuse and the relay. If it comes on then you know the fuse and relay are good. Replace the fuel filter. If that does not help more than likely the fuel pump is bad and needs replacing. The pump can run and still not be pumping any fuel. A fuel pressure test will verify if the pump is for sure bad. You have an 11 year old vehicle so it would not be uncommon for the pump to go bad especially if the filter has been neglected. A partially clogged fuel filter will destroy an otherwise good fuel pump. You will have to remove the fuel tank in order to replace the fuel pump. Use a hand pump to remove as much fuel as possible from the tank as gasoline weighs around 8 lbs per gallon. The less weight the better. Good luck and Merry Christmas.
