My XL7 won't start immediately after I fill it with fuel. It does not matter if I fill the tank or only put a few gallons in. It has no other issues running or starting. Can someone please put me on the right track to fixing this issue? From other forums I have read, it might be the purge valve, but I can find very little info about that.

doesnt make a whole lot of sense. never having worked on a suzuki i think i would find the fuel pressure specs and see if its on its way out. the way purge vavles are on a gm it would never stop the vehicle from starting, it will just be a vaccuum leak if the purge vavle is stuck open

I don't know much about how all that works, but basically the other discussion said that it was the equivalent of flooding the engine when you filled it with fuel. Again, I am not a car savvy person. The explanation made sense to someone who didn't know any better. The XL7 is basically a Chevrolet Equinox (built in the same factory) with different headlights. Thanks for replying.

So you have the 3400? If you block the line to the throttle body from the purge and make sure the vacuum is plugged see if it makes a difference. Going to get a code obviously

I don't know the code. I don't work on cars. I took the car to a shop and they ran the code, but all the guy could tell me was that it has something to do with the emissions system. My check engine light is on, but I don't know the code. I was hoping this was something easy I could do at home.

was asking the type of engine. try plugging the line and filling it up

sorry, like I said before, I don't know much about cars. It is a 3.6L V6, that is all I can tell you. So I need to do that before I fill up? Will it fix the issue, or just temporarily bypass the issue so the vehicle will start. It is only the first start after the fill-up. It runs fine otherwise.

there is a number of things it could be, if you plug the line and it doesnt do it any more you know its something with the evap system. you cant leave it that way it will give you a code or two for evap purge flow
