Title: Fuel pump squelch stopped - starting/running fine!
Post by: SilverBeast on August 16, 2014, 03:10:52 PM
I noticed in the last few days that I no longer have the "squelch" when I turn the ignition on.  The car starts and runs fine (though I have only been doing my 15/20 min commute journeys.

I changed my oil and replaced all the filters last weekend. 

I can't say for certain when the squelch went AWOL as it has had the service now warning for a couple of weeks, so I only noticed it's abscence once I had cleared the service message and filled it with fuel (so there were no beeps when turning the ignition on).

Any ideas?  Would relay 109 cause just this or would that cause other problems too.

I have read of a pump in the tank, but can't find it (or the electrical connections for it) on TIS

There was another post on here regarding this a while back, did you change the fuel filter at the same time? IIRC he changed that and lost the noise with the new seals... it'll be back after a few months lol.

I renewed my fuel filter and seals recently which seems to have helped with starting (it did chug over a bit and tend to splutter into life sometimes previous to this), so the old seals must have been letting a bit of air ingress into the system. I do however still have the squelch!

There is a lift pump in the tank itself as well as the mechanical pump which is run off of the camshaft. I also believe that the designers commendably installed an access flap under the rear carpet above the tank which allows you to access the lift pump without dropping the tank!

Hi Mirez
Yes I did.  It didn't have new 'o' rings supplied with it this time (it was full Mann filter kit from gsf via  [eBay]  http://www.ebay.co.uk/itm/300985125180?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 (http://www.ebay.co.uk/itm/300985125180?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649)

Hi inasanitybeard
That's the pump I was looking for on TIS put couldn't find reference to.  I assume its combined with the sender.

Even the genuine Ford filter doesn't come with the O-rings which seems daft to me, especially as they tend to compress and become less flexible over time so they don't seal fully, it seems a given to me that they would be supplied with a new filter as that's when you'd expect to change them!  ???

I believe, as you say, that the lift pump is integrated with the tank level sender unit.

The others I have changed have always come with 'o' rings - usually cheapies from ebay.

I'm not too concerned though as they were changed last year and it was a tight fit getting it back in.  More concerned that it seems to get harder each year to disconnect the other two hoses from the filter, and that I couldn't get the connector for the wipers off, since I broke the release clip a year or two ago!  Must mean they are due to seize again soon :)
