Was there any resolution on this? My wife's 2010 G6 GT is having this exact problem. Every other day or so, the car will crank but not start. The temporary fix is removing and reseating the fuel pump relay in the trunk fuse box. It will go several start cycles but will fail again within a few days. Taking out and reseating the relay enables it to start again. I don't believe it is the fuel pump because it runs fine once started. I have replaced the relay but that did not fix it. Could it be related to the anti-theft system, like it somehow forgets her key? If so, why would reseating the fuel pump relay fix this? Confused in Indiana. Thanks for any suggestions.

Bemo,

Don't replace the fuel pump until you verify the fuse box itself. I had the same issue with my car and I replaced the relay twice (returned a good one thinking that they sold me a defective one). It turned out to be that the ground connector in the fuse box to the relay (when the relay false it gets hot). I re-solder the cable to the connector and the problem was resolved. My car had 98k miles when this issue appeared and drove an additional 35k miles before trading in the car without the issue reappearing.

Hope this helps!

Rvega, Thank you for the suggestion. You were right on the money. One of the wires/connectors going into the back of the fuse block was making an intermittent connection. I found the right wire because the gray plastic around it on the back side was a bit brownish like it had gotten overly hot (a bit disturbing isn't it?). I was able to remove the wire and spade connector from the block and then solder the connection. You helped save me a bunch o' cash. Thanks again!
