Question about GMC Canyon

When I release the gas cap to fill it, there is alot of pressure that bleeds off. Then the gas won't go in not even really slow. When Ido manage to get gas in the tank it will crank for a very long time befor it will start. Can anyone help me with this problem? Thanks Mistyann

Sounds like the evap valve. Fairly easy, although potentially time-consuming, repair. The entire evap vale assembly should cost under $200. The assembly is right in front of the fuel tank under the truck.

Does a 2012 2.5 Ford Fusion have a coolant bleeder and if so where is it located ?


Maintenance and Specification hen you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
• 2.5L coolant bleed valve coolant bleed valve 5. Open the coolant bleed valve on the back of the engine water outlet
for the 2.5L engine or in the thermostat housing for the 3.0L engine.
6. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the COLD FILL RANGE or the FULL COLD level on the reservoir.
If you removed the radiator cap in an overflow system, fill the radiator
until the coolant is visible and radiator is almost full.
7. Close the bleed valve and reinstall the cap on the coolant reservoir.
Turn the cap until it is tightly installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
to Checking engine coolant). If the concentration is not 50/50
(protection to -34°F/-36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.

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 ran out of gas and now my car wont start. Tried turning the key several time and no luck


ON your fuel rail under your hood is a pressure release valve. It looks like your tire inflation valve. It may have a black cap. remove cap, turn on key, then turn off. press the valve to release the fuel pressure. do this a few time and it will bleed your system off excess air. sounds like you have a vapor lock.

My mini is using alot of coolant we think the thermostat is blocked, its pressuerising it back through the resevoir


Most common coolant leak is from the thermostat housing seal. Replace seal or housing and bleed properly.
Loosen plastic bleed screw on pipe above fan belt. Fill coolant via pressure cap ( right had side of engine....not expansion bottle) tighten once coolant free of air is seen. Run engine, loosen other plastic bleed screw on heater hose ( towards bulkhead ) and retighten once coolant runs free of air. Top up via cap again, run engine at 2500 rpm for 3 minutes with heater on ...should be very warm now. Once cool, check level and top up as required.

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.

Every time I fill up my 2001 Hyundai Elantra at every station I've been to the pump will constantly cut off during fill-up. I've tried pulling the nozzle further out of the gas tank and pushed it in as far...


When a gas pump does this it is because there is alot of pressure in the gas tank. This is a good thing for you because it means all your seals in the fule system are working good.Next time you fill up open you fule cap and let the car vent for a little bit then try to fill.

Code 0440 or P0440


p0440 is typically an evaporative emissions code. What that means is gas in your tank evaporates and there is a system (evap system) set in place to manage those evaporations. This system monitors gas tank pressures and releases pressure accordingly. By monitoring pressures it can sometimes be set by leaving the gas cap a little loose after filling up. So the first thing I would check is make sure your cap is tight and get that code cleared out somewhere like a local parts store for free and see if it comes back on.

Fuel pressure release


Remove the gas cap, disconnect the battery, locate the fuel pressure test port, connect a fuel pressure gauge with a bleed off valve and drain tube.
