Won't start, please help!
 

Hey guys, bought a used cx7 about 5 months ago, it's a 2009 and have had no problems with it until about 2 weeks ago, it started dieing when it was idling or when you started to take off. Ran fine as long as you were going and the rpm wasn't around 1k or less. Sometimes was hard to start back up but sometimes not. Well now it cut off and will not start back!!!! I replaced the in tank fuel pump and still won't start. Has this happen to anyone before??? I can take the elbow off the intercooler to the throttle body and spray starter fluid in the throttle body and it will crank until the fluid runs out. Any help will be greatly appreciated!

Purge valve stuck open? Maybe? Possibly?
