Hello. My 98 blazer is setting off Evap code number P0440, which indicates an Evap emission control system malfunction. Now here comes the interesting part. When I shut off my vehicle my fuel pump stays on about 3-4 seconds longer than it should. Now, I would like to believe these two problems are somehow related. What would be your guys best guess at what is causing this? I know how tricky Evap leaks can be without a smoke test. But I was hoping with the fuel pump staying on longer than it should after shutdown of the vehicle it would be a dead give away to a knowledgeable mechanic. Also I had the fuel pump replaced approx. 3 years ago. Thanks in advance! -Andrew
