I recently had the check engine light come on, I replaced the cap and reset the code. a couple days later it came back on. When I went to get the truck inspected they said the Purge valve was bad and needed to be replaced. So I did it. Check engine light is still on and the gas cap light is on as well.

When I cut it off to get gas the truck takes 4-5 times to get it to start, its like its out of gas.
When filling it up as it runs the tank has a LOT of pressure when the cap comes off, The engine surges between 500 & 1500 RPM and it fills very slowly.
I'm sure this is a common issue, I just don't have the tools to diagnose it,and being out of work right now I cant afford a big mechanic bill

If you can drive it, take it to an auto parts store, like Autozone, oriellys, etc.
ask them to use their scan tool to check your truck.

they should give you at least code number, like P 0456
with that code, a list of possible causes will show up
