Does the fuel pump make strange noises when it starts to die
and what do they sound like?
my car makes a strange noise like an idler pulley for ac going bad it does not do it when engine is cold only after engine is at full temperature. the noise seems to be coming from rear of cab but it might originate in the engine compartment.

when your fuel pump goes out they just go out I.E. doesn't do anything at all
what i would do if you don't have power steering pull the belt off take it for a ride if it is still making noise

what you could be hearing is the alternator bearing starting to go out
it it a grind or a whine

 

thanks - blkjak

 

Mine makes the same noise. I hear it through the filler neck which is like right behind you in a crx. Almost sounds like metal on metal rubbing. Took me a while to figure out what the hell it was.

 

<U>bobjohnson</U> what was it? blkjak

 

it was the fuel pump

 

when a fuel pimp is working right you can here it ,it's like a hum ,if theres something wrong with it will grind (i retract my previous statement)

 

update - noise stops when a/c compressor is engaged - possible compressor or idler pulley bearing? blkjak
