Hi Kev,

I am hoping my brother will take a new waveform tomorrow (he finishes at lunch on a Friday)... so it may be the waveforms are better ater a couple of weeks use...

...still doesn't explain the 'better' waveforms with full load ON though...



Mike

Great. He is tempted to do a fuel presure test too, but we just discovered the Focus Mk1 has no schraeder valve on the fuel rail, so it needs to be done another way!.....fun fun fun...

Thanks, my thoughts were similar. Allow the brushes to wear in, and do another test. Wasn't sure if anyone had seen these signs before, rather than us just assuming.

Thanks Rob

Hi All, Here we are with waveforms :) Key on, Engine off. Here we have the old pump (this is where the pump runs for 2 seconds at switch on to pressurise the fuel lines). 20120622-0002 - KOn-EOff - Steady State Current and RPM.gif ..and the new pump :) Key on, Engine off (where the pump runs for 2 s...

Hi all,

Right we should be taking a better look at this on Friday PM, or Saturday AM, but we need some specific info...

Do any of you know, or can you find out the ‘good’ RPM & current for the fuel pump?


Thanks,

Mike

Thanks (again) guys. I am hoping to scope this Saturday afternoon if it stays dry...worst case I'll clear the garage ajnd do it in there, but it might be tight.

Thanks guys this is great!

I'm going to pass the information on, and try to convince him to let me at it!

Will keep you all posted, but feel free to post more info

This forum is going from strength to strength

Thanks Dan - that's a great starting point. Some additional information has come to light, DTCs. Now these were pulled from the car after the recovery chap had visited, during which time they had the pump disconnected whilst they cycled the key several times. The codes have been cleared now to see i...

Hi All, Family issue with this car, its my brothers MK1 Focus. http://cdn.motors.co.uk/d/used-photos/30491/400x/0/0/X699PPU.jpg (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 la...
