wurring noise coming and going. PLEASE HELLLLLPPPP !
Hi, I am now a proud owner of a 240 glt estate (added to my collection of a 740 slaoon and a 480 es).
Can anyone shed any light on to the 240`s very annoying wurring noise that the car emits. I have an idea what it may be. The noise is really hard to trace, it appears to come from the passenger footwell one minute then the drivers side rear the next. Must add that the noise at its worst when low on Petrol (just above the red). I would appreciate any advice you have with this "NIGGLE". Apart from that little issue i am more than impressed with the 240 and find its larger 2.3 engine far more economical than the 740 saloon and probably on a par with the 480`s consumption also. Hope you can help, Minty Last edited by minty; Jul 31st, 2006 at 10:00. |

Sounds like the classic symptoms of a failed in-tank fuel pump, causing the main pump to have to work harder, especially when petrol is low.
You can bypass the relay (bridging fuses 4 & 6, on mine anyway) to make the pumps run continuously, then disconnect each in turn to listen for the noise. If yours just has one pump, it may be worn. Possibly a partly choked filter. |

Hi, It could well be the in tank fuel pump making the noise. I had an 82' 244 GLT with similar syptoms & like yours was worse as the fuel tank emptied. I used a Volvo specialist mechanic then, and his advice was to put up with it as they tend to go on & on despite the annoying sound & in my case the cost to replace it was far in excess of the cars value. I think there are two pumps, one 'in tank' plus one other. IF I remember correctly you can pull the fuse to the 'other' pump & if the whirring gets louder (as it is now working harder) it will confirm the diagnosis. Sorry if this is a bit vague! I am sure someone else should be able to confirm the procedure I refer two. Good Luck.

Hi Guys, I have started the car and what happened is the following.
If i remove fuse 4 to the in tank pump there is no change to the running or the noise. If i remove fuse 6 to the main fuel pump the engine stops completely (the fuse is also very warm) Help anybody please ? Thanks Minty |

It looks on the face of it that fuse 4 operates the in-tank pump, which has failed or is ailing, so removing the fuse makes no difference. (That's a guess - I'd need to look at the wiring diagram to be sure I've got them the right way round.)
By bridging I just mean joining the terminals together with a short bit of wire- leave the fuses in place. Haynes describes the process. The result is that the pump(s) run continuously but without the engine running, so making diagnosis easier. If this is the case, and the in-tank pump has failed, leaving it runs the risk it is always said that the extra load on the main pump may cause that to fail too. On the other hand, the in-tank unit is expensive and awkward to extract. I think we need a few more facts first. |

Thanks Clifford, i have bridged the 2 fuses and it appears that there is noise from only one pump. I held the top of the in tank pump while the two fuses were linked and could feel no movementor vibration, i could hear noise from the tank so am i to assume this is the main pump drawing fuel ?? or is the in tank pump working ??.
I have spoken to the previous owner of the car who tells me he was aware of the noise yet had no idea what it was and because it never caused him any trouble since it started (about 6 months ago)he never felt the need to worry. Idealy i would like to remedy the problem although there is opinion that says leave it if its not to loud and i will be fine. Rock and a hard place me thinks !!!!!. Thanks Kev |

Have sourced a new pump for £40(£40 to fit) or complete secondhand unit from ebay. not really sure which avenue to go as both have risks.
Is the fuel pump in the 1.986cc the same as my 2.300 does any body know, thanks Minty |

I'm abt to buy a 244 GL Sedan Volvo car. I'm so afraid, because the owner prepared racing cars some years ago, and when I ask him abt the noise he looks "confused" and no words come from him. In few words: when the engine gains temperature, you accelerate and hear a Singer sewing machine like tick tick in the upper sector. My question is: would be a connecting rod punch? Or simply valve noise? Maybe she would lost oil pressure, or not. I don't know. Thank you in advance for any directions, suggestions or advice! Albert (from Argentina! Yeah!) http://bmwasp.blogspot.com http://racingasp.blogspot.com |
