About 3 weeks ago I drove the car from Indy to Chicago. Once in Chicago I couldn't get the car to start after shutting it off. The dash lights came on and the engine sounded like it was trying but I noticed the fuel pump was not priming. I had the fuel pump replaced and the car ran fine for the remainder of my stay. Two weeks later I drove from Chicago to Indy with no issue. After sitting for 3 days, the car won't start and has the same initial symptoms: the fuel pump isn't priming.

I've checked the fuses, which look fine. The immobilizer light is not indicating any issues with the key. The check engine light shuts off after a minute or two. Any ideas?

 

Try swapping out the fuel pump relay with a new one
