Gas pressure buildup


Replace the gas caps with new. It sounds like the vent in the original gas cap is stuck and not working.

2003 Chevrolet Silverado 4.3 V6 with MFI. Engine ran not start.


Well it could be numerous if things but you want suggestions...So here's mine..Your gas tank might be vapor locked...This is caused from over filling your gas tank with gas over the years..Its when the pressure in your gas tank becomes greater than your fuel pump. It wont start until the pressure in your gas tank becomes lower then you fuel pump...Sounds crazy...This got me once...I didn't understand it...A lot of people (including me) Go to the gas station and get that extra 50 cent after the gas nozzle clicks off...over time that extra gas will run down the vapor lines intended to burn fumes....Like when you fill a gas can to cut your grass...If you sake the gas can it builds pressure and bows up. But with time that pressure will go away...Well saying that...Your gas tank needs to vent to....So your car burns not only gas but fumes...If you keep over filling your car with the extra gas it cloggs up your vapor canister intended for fumes or vapors...The gas will will go into that canister and clogg up the charcoal that's inside it. (Breaks it down) then the vapors can't get to your carburetor where it supposed to burns it. So what happens is the pressure in the gas tank becomes greater than your fuel pump and then car won't start..Are you with me? Lol Its crazy..Putting a different gas cap can cause the same thing...Simple test...When you open your gas cap to get gas.. Do you heat air sucking in.. Yes you can hear it....A lot of times loosening the cap let's the pressure out and the car will start right up.....Thus might not be your problem but worth telling at the gas pumps to other people..... Just trying to help

No pressure in gas tank when the cap is opened.


I am not sure I understan tghe question. You should not have a lot of pressure in the tank. There are hoses that capture any vapors that are in the tank and eleviate pressure build up.
Most often I have found the engine light on because of gas tank vent, such as loose
or bad gas cap or the vent valve stuck open. The computer does a cycle ever so often
and maintains the vent pressure build up in the gas tank and vapor canister, and if the purge valve sticks open the computer gives a check engine light and code as the pressure is not in the vapor storage tank when called for.
If your worried about no pressure at all then I would change the gas cap and see if this helps

Idles nice but when i go to drive it sputters and chugs and serges what is going on? also having difficulty getting it to start have to turn switch back and forth until it starts. Also I lost gas cap does...


try replacing the gas cap first and see if it helps any, on some vehicles, the fuel pump builds pressure inside the tank so it has the correct amount of pressure to send the gas to the engine. if the cap is missing, it can't build pressure.

1994 Chevy Silverado Gas Cap Unavailable?


Autozone or oreily just any gas cap just about will do. To force open use a flat head screw driver, hammer and pliers. Drive the FLAT tip screw driver into the gas cap and use the pliers to turn. These vehicles did not come factory with locking gas cap so some one has replaced it once before. Don't worry the worst you can do is ruin the gas cap which is no good to you any way.
