Answers :

\015\012What you can do is when you get in the car in the morning, turn the key ON but do not start it. Listen to the fuel pump and when it shuts off turn the key off and back on, again not starting it. Do this three or four more times and then try to start it. If it starts right up, you probably have a bad fuel pump check valve.
