Have to smoke the system & test the components,
unless you can find a diagram of that solenoid & want
to chance the price of a part & maybe not fix it, because
of no component testing.
very easy way follow the evap canister vacuum line also it goes to under the powerv supply pat .and check the engine pcv valf line and breaking hose ,and around of the throtle ..because the vacum problem connected with this systeems
I would start with the gas cap replacement and see if the issue resolves itself. If you do have a problem with the EVAP (canister) system, it may require tools the average person does not have to help diagnose and correct/repair.
The evap system ( fuel vapor recovery system ) , if there is a leaky hose, can let fumes out that can be detected in the cab. If you "top off" the fuel at the pump you can spill fuel into the charcoal canister meant for fuel vapors only. the vapor recovery system is behind the left rear tire.
Usually if there is a hose leak a check engine light will come on.
If you TOP OFF, don't. If you don't, good. Hope this helps.
i already did came back on
