Family issue with this car, its my brothers MK1 Focus.
(Not this actual one, but it's the same!)
Sadly I can't get to him for a while, so I thought I would post the issue here rather than in the Case Study section due to the lack of waveforms (for now), however with the right info and pointers perhaps I can turn it into a Case Study for our newsletter. Therefore I am asking for your assistance, any info/advice you can offer would be appreciated
Ok, so here's the deal:
Ford Focus Mk1 – 2000 (X) - 1.6 Petrol
On and off for a while now they've been having problems with the fuel pump in their Ford Focus.
Sometimes it blows the fuse, sometimes it doesn't, but either way what they end up with is a pump that isn't priming the system when the key is turned to the position before cranking.
After much retrying and general fiddling with the wires and gromet etc to the pump under the rear seat the pump will usually spring back into life, but there doesn't seem to be any rhyme or reason as to why / when this will happen.
At the weekend they had the recovery truck out as after the normal amount of fiddling the pump was still not playing. The guy did all the usual checks on the fuse, checking for supply etc, then lifted the rear seat and removed the large gromet that carries the wiring to the pump.
Disconnected the connector and checked the various connections using his meter. Again all the readings seemed correct, and when he reconnected it to the pump the pump primed and the car started fine.
However, my brother's wife (who drives the car the most) has now reported that the car feels 'lumpy' and 'hesitant' so it could be that the fuel pump is on it's last legs.
I offered to scope the car before, but due to it being such an intermittent issue he never saw the point as he said the fault wouldn't appear knowing his luck. Now his wife reports poor running, I am thinking its time to swoop in....
So ideas... ? If you believe it's the fuel pump, thats fine... if you think further investigation is required, please advise
Many thanks guys,
