Thats a good thing. Means your fuel system , which is pressurized, is working ok. If it doesn't have suction, it may cause your check engine light on. unless it's causing problems, leave er be good luck hope this helps you. Cheers from Nova Scotia!!

Hi I have a Mazda Tribute 2004 all of a sudden the emission light is on and won’t go off all the oils are good ,only had her 4 weeks has had a service when I got it please help

If when you pull the gas cap, you don't hear that quick suction loss/hiss, the gas cap needs replaced and will cause the light to come on and stay on till you replace the cap. These are sealed fuel systems.

Sounds like a bad connection on your ignition switch or wiring in the fuel pump circuit.

I can't get gas to go in my bmw 323i convertible, help? The gas cap is very hard to get off now and the pump won't suction on when I try to put gas in.

1. Unlock the gas cap. Slip the key into the slot on the center of the cap with the teeth toward the outer circle. 2. Turn the key clockwise. The lock cylinder gives and allows the key to move. 3. Turn the gas cap counterclockwise. Unscrew the cap...------------------------------------------------------------------------------

Nissan Altima cranks, but won't start. Open the fuel tank, it starts. Gas tank vent? Clogged vent line? Gas cap?

no it has a closed system so no smell of petrol so their is something wrong with the suction pump and the pipes that come from teh engine compartment

The engine runs fine until it get to half a tank of gas.

I wonder if it could be that the tank's not getting vented properly... have you tried just taking the gas cap off and replacing it, without adding fuel? is there a suction sound when you take the cap off?
