Hello all,

Don't know if anyone can help out with this technical question but worth a
try.

The Subaru Fiori maybe called 'Rex' or 'Ace' in other countries, not sure.
Anyway this one in Australia has the 758cc engine.

We have a 1991 Fiori, unbelievably great little trouble free car up until a
few days ago. She just stopped, so we called the NRMA (mobile mechanics) and
the guy said the fuel pump has packed it in. We have a service manual for
it, so I had a look at the drawings and see that the pump gets it's power
from what is called a 'Revolution Sensor' which in turn receives a signal
from the coil. The 'Revolution Sensor' has a circuit board inside which
means it is all quite complicated (computerised so to speak). Tested the
power from the 'Revolution Sensor' and it gets 12 volts ok but no amperage?
Anyway, to make a long story short, I tested the pump with a direct 12 volts
and she works fine. So I tried to find a new or second hand 'Revolution
Sensor'. In NSW there are none in existence. The dealerships say they are no
longer in stock and the wreckers have scrapped all the bodies, whilst
keeping only the 'quick selling' parts. The sensor box is mounted under the
dash above the fuse box (about the size of a small pack of cigarettes).

So my question to you all I guess is, do you know if it's ok to run a
permanent power supply from downstream of the ignition system to the pump,
i.e., the pump would be running flat out whenever the ignition is on,
without any variation in petrol supply from idle to maximum revs? It has a
fuel return
line to the tank so in principal it may work but what worries me, is that
they went to so much trouble designing this 'Revolution Sensor' that I may
be overlooking something.

Thanks in advance everyone for any help or advice,

Graham

I don't know who you are "number 9" and I don't know what "The 2 posts above
are virus crap!!!" is all about but I certainly hope it doesn't interrupt my
chance of getting some valuable help off any of the knowledgeable people in
this news group.

One thing I can ensure you and everyone else, is that this and my previous
post has absolutely nothing to do with any virus. Wherever did you get this
notion?

Could you please explain what this is about?

I think there is some misunderstandings here...
I don't know who you are either, and frankly, I don't care %-)
Before you get too exited. I was talking about the two posts
above yours... My Avast indicated that there Viruses in those
postings... So don't get all shook up; - relax, take a few deep
breaths, and everything will be okay... That is of course, if you
don't read the above mentioned posts...%-) Try it, tell us what
happend :-)))

Sweet dreams, NUMBER 9.
(Halloween is close, booo!!!)

You obviously have a different News Reader than I do. I can't even see the
posts you're referring too.

My problem is though, you linked your message to my post, you could have at
least started a new message and said, "the 2 posts below" and left me right
out of it.

It is quite common to have a crank sensor to control the fuel, so that the
fuel is only flowing when the engine is running. Doing a Google search on
"crank sensor fuel pump" gives lots of information.

It may only be a problem if it an accident occurs or rollover and the pump
keeps gas flowing after the engine stops.

The problem may be the sensor and not the control box.

Number 9,

Someone who refers to posts in usenet (which distributes articles
asynchronously to a network of independent nntp servers around the
globe with vastly different article propagation time) by "two posts
above" and does so following up and quoting an article that's
unrelated to the one you were speaking of anyway.... um... well, has
no business being a condescending douche to anyone.

Also, you can't assume that the "virus crap" made it to everyone's
nntp server because no-cem and other canceling activity may have
removed them.

By my calculus, you owe Graham a couple apologies 1) for hijacking his
thread and being an idiot, and 2) for giving him attitude when he
rightfully busted your balls for 1.

Graham's message you uqoted this with is plain text and contains no
virus. Report it to Avast as a false positive.

And please don't top post.

Thanks for your input Blair, appreciated. I had a look at a few of the
Google sites you mention but I'm unsure whether this Fiori has a sensor tied
in with described cranking as such. I will add that since my original post I
have left the 'Revolution Sensor' intact but have cut into the power supply
wire to the sensor and joined it into the power to the pump downstream of
the sensor, in effect bypassing the sensor control. The car is running well
but I am unsure of the consequences. I have also since learnt off list, that
the 'Revolution Sensor' is now called a 'CFC Unit' in Australia and the
Netherlands with inputs to a few other gadgets, called 'Slow cut-out valve'
and 'Boost switch'. Gawd, fingers crossed.
