Problem started with evap purge solenoid valve going out. Changed that but now everytime I fill up with gas, the truck acts like it has lost it prime. Only does it when I get gas. I have tried removing the gas cap and letting it sit for a while but it fires right up. After getting gas, it will fire back up after cranking it a few times and will not do it again til I fill up again. Any ideas?
