I'd like to know too! Mine does the same thing - it makes a rattling noise upon startup that goes away after 30 seconds or so and isn't present while driving or idling.
Fuel pump
Yes, every once in a while while driving your air compressor will kick on. If it seems to be running nonstop there is a problem. You would have a hole in one of your air bags if your compressor runs nonstop. Hope this helps.
Bad ecm
Is the engine running ? no
when i am driving my toyato 2001 Eaco stops running, it will start back up
There are 2 fans that would be running while you are driving and that is normal... the compressor fan if you have the air conditioner running and the radiator fan runs to help keep the radiator cool while the engine is on.
yes.
You've run out of fuel...
1998 that when
There can be a slight humming noise while driving a neon. This sound could come purely from the engine to indicate that it is running.
is your check engine light on? and what kind of Lincoln is it? its probably becasue your car is NFG or POS
