2007 GMC 1500 Fuel Smell

Here's another link I found that goes into a bit more detail on code P0452 that may help and explain the fuel smell >>> http://www.obd-codes.com/p0452

I guess my big question is, is it still safe to drive?

 

I also just went out ( dont make fun of me ) and opened my gas cap ( instant gas smell ) took off, checked gasket, put back on and clicked a bunch of atimes to make sure... i will test and verify. Check the dumb stuff first ( always my problem, jump to the big issues first )

I too was starting to wonder if it's just an issue with your gas cap?

Im a network admin not a car mechanic LOL But before my father in law passed away he showed me all kinds of neat stuff.. We just never got into Fuel or engine internals.

P0452 traces back to Fuel Tank Pressure (FTP) Sensor Circuit Low Voltage. Common part to fail on these trucks.

Too F'in cold to tell if theres a fuel smell last night, today, tomorrow and thursday... F'in -5 without the wind chill this morning... FACK!

I hear that. Even way down here in MA we've been at 10° for the past 8 hours. Tomorrow or Thursday we'll be getting negative temps ...

 

Glad I just fabricated a waste oil burner for my barn. Out there fixing crash damage on our '89 S10 Blazer - wife slid off the road and cranked a guardrail last Saturday after the snow ...

 

Gotta love winter!

I have a backup K1 heater that we lit last night because it's so windy and cold... New siding and insulation on outside of house and windows and it still a biotch to heat. Takin the edge off with the heater where we need it... HATE COLD WEATHER! Time to move south... thinking something tropical.

UPDATE UPDATE:

Soooooo, i walked by my truck the other day and my Hubble Telescope eyes managed to catch the top of my fuel tank between my cab and the bed of my truck ( Perfect view )

Looked down and that lock ring looks BRAND NEW, black... no rust... But i can see some wetness ontop of the fuel tank. In the next week or two I will be pulling the bed off to get a better view but if I had to venture a guess I can see some lines there that look weathered.... We shall see.

UPDATE:
It got worse so I stopped in at my local trusted mechanic and had them do a diagnosis. Fuel supply from pump was rotted out. Had them just do it because I dont have the time changing jobs and because I need reliable transportation.

Should be fixed later today.

Good deal.

839$... they marked the parts up 40% ( Seemed high but thats the norm around the area ) and I knew the guy who was doing the work and trust him.

I have a 2007 GMC SIERRA 1500 and every so often I smell gas in the cab of the truck. This truck only has 38K on it, and no indication of engine problems. So where would the gas be leaking from? Fuel filter, sender unit, evap canister? What usually goes wrong on these trucks?
