I have a golf GTI mk5 . It was idling for about 5 minutes then it shut off and will not start up . It will crank but not start up the fuel pump is fine wen ignition is turned on the ECU boots up fine . Wen I crank the Rpm doesnt move but I replaced the crank shaft sensor and still no RPM wen I crank and it still doesn't start up . No check engine light. I also realize wen I turn on the ignition I get three loud beeps not sure if it's because I'm low on fuel .
