NOW I know this would usually be diagnosed as a failing pump... I'll give some background before you jump to that one

Car has been relatively unused for a number of years, just been MOT'd and cleaned up

Fuel gauge not working, moves up a little but not out of the red.
Fuel Computer gives accurate information, including range left in tank.

Drove the car bout 50 miles up motorway, pump making real loud buzzing and spitting noises, as though is cutting out, car wount run, leave to cool for 10 mins, then fine. BUT problem re-occours.

Fitted a Secondhand pump, took the car out, litterally 2 mins down road, SAME symptoms...

Tried with feul cap off, so not a vacum prob.

DEFO got fuel in it.

Could something be in the tank blocking feed to pump?... the car has been used briefly prior to this problem covering about 30 miles...

Have we simply got 2 dodgy pumps???

 

They start buzzing when as you say they are on the way out or if the fuel lines have a restriction, have you changed the fuel filter? the problem has all the symptoms of this being blocked. If so then you may of got 2 dodgy pumps, try running the car and when it cuts out check the fuel pump if the area around the contacts is hot then this is a sign it's on the way out- an internal electrical/ mechanical problem will cause the terminals to get hot as the pump pulls more electrical load to compensate for high internal mechanical/ electrical resistance.

Tried the relay?

 

Its worth swopping the relay for another one that you know works then testing that.

I had the exact same symptons as you (even down to the running fine for 10 minutes once it had cooled down a bit) I fitted a brand new fuel pump and it cured it immediately I reckon you might have two fucked pumps.

 

Thanks peeps, a good number of excellent suggstions.... will see how it goes

 

SORTED


It would seem where the car has been standing for so long, with a little fuel in the tank, it had caused the inside of the tank to corrode heavily, presumably the pump was trying to pick this up, instead of fuel!!

S/Hand tank, ALL sorted... so it would seem

cheers guys...

 

Good to hear mate
Wish everyone would leave feedback/resolutions then it saves reading/replying to the same problem over and over
