Re: 2008 jgc starting problems
No not a temp sensor , a line that was kinked so it was building back pressure from the fumes. It would run fine then you would park for a bit then it was hard to start unless you let it sit for 5-10 minutes with the hood open. It eventually let some of the pressure through , and this only happened when it was warmer out due to heat expansion in the fuel. That gas vapor needs to vent , some have a charcoal canister under the hood , and some have that and/or just a little vent line right off the tank with a little plastic piece in the end , kind of like a check valve to keep water out but let the vapor out of the tank.If you follow the lines off your tank you should see your fill going to your gas cap , a supply and return to your throttle body and one either off the tank itself or going under the hood also for a vent.
