Is my fuel pump going bad? Here's the symptoms.
My fuel pump just starting making some strange buzzing whining muffled sound when i turn the key to the on position. A couple of times it didn't make any noise at all and the engine was just turning over. 
Any input would be nice.
Thanks...

It used to make a little noise when priming but now it makes aLot of noise.
Doesn't sound right. Sometimes no noise at all.

I vote for a bad pump. A bad main relay wouldn't cause the pump to get MORE noisy.
How about a fuel filter that's gotten plugged up? Then even a good pump has to work extra hard against a blocked filter. But that doesn't explain why sometimes it just doesn't run at all.
