Hey folks,
I have a 2007 Canyon with 120k miles on it... Up until now, I have had no issues with the gas tank, as I know these trucks are notorious for the top metal ring rotting out and leaking... The other day, I filled the tank, and after a short drive, I was standing next to my truck talking to someone, and I caught a whiff of gas... I put the truck on the hoist, and pulled the fender liner out and sure enough, the top of the tank in the indentation where the fuel pump goes, was all damp with gas... I figured I was in for a new tank, until I noticed another strange problem cropping up.... First thing in the morning, and every time the truck sits for a while, it winds over longer than normal before starting... Normally it will crank for 1.5 seconds max before starting... First thing in the morning, I am looking at 4 seconds or so of cranking before fire.
Now I haven't dug into anything further, I will when I get more time, but this sounds like a pump or line problem doesn't it? I am sure that the tank top is bad as well, but that would not cause it to lose pressure in the fuel line between starts.. Sounds to me that when I shut the truck off, and it sits with 40psi in the line, that eventually it leaks out on to the top of the tank, and when I crank it over again, it needs to pump and crank longer to prime the line again...
Am I way off base here?
