My 2013 Impala has a 3.5L engine. I came home from work and ate supper. Then I went outside to start the car again. The engine turned over but no start. Tried again several times, finally started but ran rough for a little. Now it runs fine. Set a code P069E. Does this sound like a fuel pump module is going bad? The car has about 80,000 miles on it. This is the first problem I have had with the car. Possibly a fuel pump relay going bad? Just trying to figure out whats the USUAL culprit!
