To much pressure on gas tank when i take cap off, alot of pressure help me on my 2007 chevy tahoe


There is pressure and yes it can be allot. Unless the check engine light is on there is not problem. My Corvette really gets pressurized when i remove the cap, esp on hot days, have had 2 of them both did the same think. the system can build up to about 7 PSI and that is a real pop when you pull the gas cap.

I have a 1999 Monte that builds pressure in the gas tank and need help because it has pop two gas tanks why is it building pressure .


Back by your tank, there is a vapor canister with a vent valve on it. That valve is supposed to let vapor from the tank into the canister. Check to see if the valve is working. You can test it by connecting it directly to the battery with some jumper wires. Once in the canister, the vapors are opened to the engine vacuum for burning by the purge valve once the car is warmed up and on the road. If the vent valve is working, but pressure is still building, the problem can be the purge valve at the engine. You can tell this is the problem if the cannister is full of liquid gas. Normally, and depending on the failure mode, these failures would set the engine light. If the light is on, get a scan to see where the problem is. Please let me know if you have more questions, and thanks for using FixYa.

Gas is being forced out of the fuel tank when the vehicle is running.


A defective fuel pressure regulator (located on the fuel rail) may have blown the gasket on the
fuel pump (located in the gas tank).
Another thing to check - the car's computer may have posted
an error code from the fuel tank pressure sensor.. I'm not sure, but if this sensor shows pressure
building in the fuel tank, rather than let it explode its seals, the sensor may intentionally leak fuel
in order to relieve the internal fuel pressure build-up inside the fuel tank.

On the fuel rail (supplies fuel to the fuel injectors on top of the engine), there will be a Schrader valve,
which is your connection to connect your Fuel Pressure Gauge to your car's fuel rail.
Give it a check, but put a shop rag around the connector as your screw it in - fuel (and fuel
pressure) will leak as you install the fuel gauge.

You may get computer diagnostic codes P0158 or P0159 - see below for interpretation.
Note that the PCM is the Powertrain Control Module, which is the car's computer.
Also "TP sensor" is the throttle position sensor.
---------------------------------------------------------------------------------------------------------------------------------------
Trouble Code: P0158

Meaning: HO2S-22 (Bank 2 Sensor 2) Circuit High Input

Possible Causes:

Fuel system is too rich (fuel pressure too high, fuel pressure regulator leaking, or one or more fuel injectors sticking/leaking)

HO2S element is silicon, water or fuel contaminated

HO2S signal circuit is shorted to system power (B+)

HO2S signal tracking (water intrusion) in the connector causing a short between the HO2S signal and heater power circuits

PCM has failed

----------------------------------------------------------------------------------------------------------------------------------------
Trouble Code: P0159


Meaning: HO2S-22 (Bank 2 Sensor 2) Slow Response

Possible Causes:

Exhaust leak present in the exhaust manifold or exhaust pipes

Fuel system is too rich (fuel pressure too high, fuel pressure regulator leaking, or one or more fuel injectors sticking/leaking)

HO2S element is silicon, water or fuel contaminated

TP sensor element broken (can cause false acceleration event)

Wen i turn on the Pontiac it runs good for like 7 seconds and thin it turns off i don't know why it dose that i need help?


Get a full systems check, it's probably a bad fuel pump. which means your engine isn't sucking in enough fuel to keep it continuously running, you probably have alot of build up as well, try system cleanser, put it in a full tank of gas and see if it can stay running long enough to remove some build up. Otherwise you have to go to a mechanic.

hope it helps

SOUND LIKE YOUR EVAPORATIVE EMISSION CONTROL NOT WORKING.SCAN VECHICLE FOR FOR FAULTY FUEL TANK PRESSURE SENSOR MALFUNCTION.AND THE CANISTER PURGE SOLENOID VALVE OR CANISTER VENT SOLENOID NOT WORKING.CAUSING EXCESSIVE FUEL PRESSURE AND FUMES BUILD UP IN FUEL TANK.CHECK CANISTER IT COULD BE GAS SOAKED NEED REPLACING OR VACUUM LINES GOING TO CANISTER PURGE SOLENOID OR VENT SOLENOID COULD BE BROKEN.PURGE VALVE LOCATED ON THE LEFT SIDE OF THE ENGINE ON A BRACKET AND VENT SOLENOID LOCATED ON A BRACKET NEXT TO FUEL TANK.CHECK BOTH MAKE SURE VACUUM LINES NOT BROKE OR DISCONNECTED.MAKE THE ELECTRICAL CONNECTOR INTACT ALSO.FUEL PRESSURE SENSOR ON TOP OF TANK ON THE FUEL PUMP MODULES.ALL YOU CAN DO IS REMOVE CANISTER SEE IF FULL OF GAS REPLACE IT.AND CHECK FOR BROKE AND DISCONNECTED VACUUM LINES.THE DEALERSHIP HAS TO HOOK UP DIAGNOSTIC EQUIPMENT CHECK IT OUT.BE CHEAPER BECAUSE ALL THEM EVAP PARTS NOT CHEAP THAT WHY LET DEALERSHIP SCAN IT SAVE MONEY IT WILL CUT THE COST.WARNING DONT KEEP DRIVING VECHICLE.GAS VAPORS PRESSURE BUILD UP ON HOT DAY FUELTANK WILL BLOW UP LIKE BALLON.PRESSURE KEEP BUILDING UP.

Gas gage isnt right it keeps floating


The Sorento gs tank is under the floor in the back seat. Flip the seat bottom's forward and pull open the Velcro to access the top of the tank. The fuel pump and sender may be accessible from the top, but you might be unlucky and have t remove the tank.

Over heating 1988 jeep comanche


You'll need to find out if the system is overheating and that is causing the the antifreeze to blow-over. If it was the head-gasket it usually would blow-over as soon as you started it up. But you say it happens after ten minutes of running. Sounds like the antifreeze isnt circulating. You'll need to check the cooling components one by one. Hoses, thermostat, radiator, water-pump.

2004 hyundai accent. trouble filling gas tank


I have a 2005 Hyundai Accent, It is not possible to fill the tank if you are letting the petrol pump run at full speed.Trying to fill up quickly it will only build up pressure and cut off. Next time you fill up just pull the petrol pump handle half way, it will take longer to fill but you wont get the blow back. Modern petrol pumps are getting quicker all the time.Hope this helps you.

Gas gauge seldom reaches full


your fuel tank has a float on the inside with the fuel pump. The float tells your guage where to read. You could check your releif hose on your tank to see if it is clogged . if it doesn,t get air out as fuel goes in it will cause the gas pump to kick off as it thinks your tank is full. when filling up just pull the pump nossel out some and see it that helps
