CHEVROLET IMPALA FUEL PUMP PROBLEM

2003 Chevrolet Impala • 170 miles

My car shut off for no reason ive had 4 mechanics look at it and no luck they told me it was the fuel pump then the mass air flow sensor then a throttle body position sensor then the spark plugs. Ive even took it to the chevy dealer and they told me vaccum leaks please help me.

Whenever I can be going 60 and it shuts off or I can be going 20 and it shuts off

Does it start right back up?

No the only way I can get it to start back up is either wait 4 hours or spray some starter fluid in the filter like toward the throttle body. And I dont want to keep doing that because im pretty sure it will mess up the car even more

Then it is fuel delivery issue.

If the fuel pressure is correct, something in the injector area may be the culprit

So maybe it could be the fuel pump again because the fuel pump I got my dad got it from the junk yard

Bad move, never, never use used parts in critical systems as this,
