Nick, Try this test: Access the electrical compartment and while the engine is idling remove fuse # 7 which will shut the engine down. If the noise is eliminated you may have a defective RPM relay. Your hot start problem may be related to a defective fuel accumulator.

It is sort of a pulsing/groaning noise that repeats about 4 times before it stops.
