Question about 2001 Oldsmobile Alero

Pressure to the gas tank?


The check engine light came on in my Alero months ago. I had the codes read and was told that there was a problem with the pressure to my gas tank. They thought it might have been a problem with the gas cap not being on tight enough, but the light still won't go out. What else could be causing this? I know when my tire pressure light comes on every other week that it's a matter of checking the tires and resetting the sensor...could this be a similar problem?

2006 Mercedes-Benz c230 will not start

At 12.3 volts you are down to about 50 % of battery and if you are going to attempt to start it again the battery should be charged so the engine spins at a nice fast rate. Having said that have you checked for spark? Is there an ignition fuse?

And I would try the code analyzer. Nothing to lose and all to gain.

What does code PO453 mean

the evaporative emission system (EVAP) control system pressure sensor has sent high voltage to the ecm or engine control module and triggered this code either the purge valve located under the car by the gas tank has gone bad, or the charcoal canister has become gas soaked and is pressurizing from gas fumes, or the sensor or wires have shorted , there is also a secondary valve located und the cover of the intake that should also be checked for shorts that can trigger this code but usually it is the one under the car that goes out 9 out of 10 times it is from fuel being burped into the evap canister or charcoal canister from the gas tank which is caused from overfilling the tank or mid day heat of 90 or better with a full tank

I just used it a few weeks ago and it worked fine. I put the rest of the gas that I bought maybe 4-5 months ago in the tank to fill the tank half full. It always started in past on 1 or 2 cranks every...

Assuming the car is getting fire from the coil and dist., I would put a shot of starter fluid in the throttle body and see if it starts, You may have a plugged fuel filter or fuel pump. I would also check the cat and muffler to be sure they are not plugged. If they are the back pressure on the engine will not allow the fuel into the cylinders and thus not fire the engine. Hope this helps.

It may just be the fuel pump seal at the top of the tank. it has to be dropped for a definite diagnosis. It is rare but the tank seams occasionally crack too. Good luck.

My Toyota Avalon 02 is experiencing problems with check engine light flashing when idling at a light and then goes solid when driving. The codes read p0300 Thru p0303. The car idles very rough and shakes...

code p 300 is random misfires
code p 0301,-2,-3,-4,-5,-6,-7,-8 all refer to the cylinder that is misfiring ie p 0303 is no 3cyl misfiring
many people mistakenly believe that a misfire is from the plug, wires distributor when in fact it is more likely to be a problem injector ---dirty tip , low fuel; pressure , blocked tip, injector wiring
using gas conditioner sometimes works but in many cases it dislodges gunk that blocks the tip
At this point I would get a fuel pressure test done to check the pressure regulator , pump and filter condition as everything you describe points to fuel and injectors
AS a point of interest- with ECM controlled engines, the ECM tunes up the engine 60 times a minute to keep it within parameters and the plugs will last the life of the engine
when you want to do a tune up , simply have the fault codes read and fix only what comes up

Service engine light on. Gas tank fills to 3/4 and clicks off. The model is XG350L 2004. The problem began about 2 months ago. It has been worked on once to replace a vacuum valve but still didn't fill up...

Did you have the fuel pump changed? They might of bent the electronic float assembly in the gas tank causing it to read 3/4 full.and making the check engine light come on.

2002 kia rio rxv check engine light came on again..

the check engine light is not caused by any wrong fluid level or dirty air filter or anything else like that, it is caused by well over 100 faults that can occur in the computer controlled electronic engine and emission controls, u will need to go to a Kragen or Autozone parts store and get a free OBD 2 fault code test to get the code that set your light.

Gas gage constantly says full when it's not!

Unfortunately this is most likely the fuel pump module, which includes the fuel level sensor also. This should be diagnosed more thoroughly with a scanner, a good scanner will be able to check instrument cluster separately to confirm the gage is working right,and check for trouble codes that may not light any warning lamps. Hope this helps. Rate me please.P.S. Dont use that fuel station any more.
