my wife's 2010 rav4 stopped at the middle of the highway. she tried several times to start the car without success. the car cranks but doesn't start. left it for several minutes, she started the car and it works. She drove home and parked the car. the next day the car refuses to start. It doesn't show the check engine light or any warning light on the dash. I'm suspecting the fuel pump but not sure about that. Any ideas of what maybe wrong with the car?
