How many cylinders is a malibu classic? The car is waisting a lot of gas for the cylinders that i think it is.

have you done a compression test on all cylinders ? if no then do so ,find the problem cylinder possible valve hanging open thats possible ,that would mean looking under valve cover

There are four things required for an engine to run: air, fuel, compression and properly timed spark. If you have fuel and timed spark, the only two variables are air and compression. Air is not the likely problem, and compression should be good unless you blew a head gasket or the rings in all four cylinders. How did you determine that you have fuel and spark? Those are the two most likely problem areas.

Check with the auto parts store to see what the fuel sensor looks like, It should be accessible and I have seen those go on the smaller chevys like aveo.
Look up on internet replacing gas recirculation sensor on google

A poor electrical connection in the circuit to the A/C pump. A lot of times it is a simple splice needed near the pump. As the lines on gas (freon or any other) when compressed, get hot. It's easy to accidentally let one of those wires hit a "hot" spot during other activity, under the hood. CHeck that the connection on the compressor (or if 2 connections) are clean, & secured.

Hi, you may have it flooded. Try holding the accelerator all the way down while cranking the engine to clear the gas out. Let us know if this doesn't work, and thanks for using FixYa.

I have the same problem right now. I am going to buy a new gas cap (since that is the cheapest possible fix) in hopes that will be why it's on. I am getting the code P0455 and that is a possiblility. fingers crossed. LOL

Hello pass.... The fuel pump is in the gas tank. The malibu does not have any fuel filters it only has a strainer on the fuel pump itself. You will have to drop the gas tank to get to the fuel pump.
The Malibu Classic (8th letter of VIN is "F") with the 2.2 Ecotech 4-cylinder engine has a fuel filter between the fuel tank and the rear axle. One end of the filter has a threaded connector and the other is a typical compression style. Regarding the antitheft system, if that is the problem I recommend that you contact an autoelectric repair shop and get them involved as they have the diagnostic tools and the wiring diagrams to get to the bottom of these complex devices.

On the V6, there is a drain plug on the bottom of the driver side plastic tank. On the 4 cylinder, it's on the other tank at the bottom.

Good luck (remember comment and rated this).
