I own a 04 silverado 5.3L ext cab 4wd. Engine lite on, tighten gas cap displays (3rd new gas cap) and just started to have a problem adding gas. the pump shuts off every few seconds and sometimes gas...


The problem pump gas is a common problem with the gas pump it self try turning the handle slightly to either side this may allow gas to flow better. The second problem the service engine soon light comes on for many different reasons not just the gas cap. auto zone usually will scan your computer for free and tell you what the diagnostic trouble codes are. find out and let me know and we can go from there. Good luck.

Check Gas Cap alarm comes on and engine light is on


You gas cap is not on tight enough to seal causing the Check Engine Light to come on. When you tighten your gas cap you need to tighten it until it clicks at least 5 times, if it is tight than the seal on the gas cap may be bad. Replace with a OEM GM gas cap or a quality replacement that meets OEM specs.

2004 Pontiac Grand Prix, check gas cap


Could possible be the Fuel Tank Pressure Sensor. It is located on top of the fuel pump. The fuel pump access is located in the trunk, under the carpet, behind the back seat. The AutoZone part number is SU 1390.

99 lexus es 300 chk engine and trac lock lite on


I had check engine light and TRAC OFF. OBD-II MIL code was P1133 which is Air Fuel Ratio Sensor Response Malfunction and scanned by AutoZone. After disconnecting the battery for 10-15 minutes, the lights went off. I cleaned the gas cap and tightened it firmly. For the last 400 miles, the lights have not come back. When scanning using Snap-on one, no code was detected. I think gas cap was the reason for the lights.

Gas Cap Error with Check Engine light


By "Replace the gas cap", do you mean put it back on, or buy another one? If you fuel these trucks with the engine running, or don't tighten the gas cap, the light will come on. It will also come on when the seal in your gas cap goes bad. I have had to replace the gas cap on my jeep and dodge already. It fixed the problem both times.

Engine Light/tighten fuel cap


Good Day,

Sounds like your fuel cap needs to be replaced, there is a rubber seal in there to which keeps fuel pressure up, when this seal goes bad you get a drop in pressure and your engine light will come on. Replace the cap with a new one. As far as your lighter ports that is probably due to a blown fuse and unrelated to the fuel cap issue.

Hope this helps
