So I have this ultra-low-miles, 11K mileage Impala SS. It's my daily driver. After it sat for about five days I went to start it and I had to try three times to get it to start. It turned over, acted like it was starting, and revved down like keying-off. Before this, after sitting overnight it would do the same, but only once, starting the second time.
When it did it once, I did try turning the key to on to let the fuel pump pressurize, but on then trying to start it I still had the same problem.
Any suggestions? Had it only done it the one time I wouldn't be worried, but now that it has required more than one attempt at a single sitting I'm getting concerned.
