Subject: DML: Down Under DeLoreans
Apparently (according to several sources on the www) two right hand
drive DMC-12s were originally shipped to Australia. I was wondering if
anyone would happen to have any idea whatsoever what happened to these
cars (c'mon, don't tell me I'm the only aussie on the mailig list :)

Subject: DML: RE: acceleration problems
Travis described a problem with his car shaking when he tries to
accelerate accompabied by a lack of power. Although this may have
nothing to do with his problem, I though I would share a similar
problem I had some time back in the event it comes in useful. In my
case the problem was caused by a failing fuel pump relay. The fuel
pump relay is an interesting device and merits a little explanation.
The fuel pump relay is connected to the tach sensor and uses the
impulse to let it know the engine is running. As long as the engine is
running the relay stays closed and allows the fuel pump to run. The
relay will open with a certain time constant (a second or two) after
it receives an impulse unless it receives another one within that
time. Essentially it's a timer that is reset according to the tach
impulse and if allowed to expire the relay opens. The timing function
of the fuel pump relay is a 555 timer chip (available from any Radio
Shack for $1.29 or so) which has a common failure mode that causes the
time constant to effectively go to zero -- the relay will in this
failure mode turn on and off at a frequency equal to the RPM of the
engine. The relay cuts out immediately after the tach sensor signal
but the rotation of the engine and the fuel in the accumulator keeps
it going until the next impulse from the tach which will enable the
relay for another pulse. Because the fuel pump delivers far more fuel
than the engine consumes and a working fuel accumulator will
effectively even out the pulses of fuel being delivered by the pump, I
found that my car still ran with the fuel pump relay cycling at the
engine RPM speed (I could hear it rattling in the relay compartment).
As the RPM's increase, the ability of the mechanical relay and the
fuel pump to keep up with the increased cycling rate decreases and the
engine becomes starved for fuel.
The relay can aften be repaired for a cost of under $2 by someone
familiar with hobby electronics by replacing the 555 timer chip in it.
Alternatively, a new Volvo fuel pump relay runs around $30-$35.

Subject: DML: Delorean video shoot
Hello Delorean Owners!
My name is Jon Wright, I live in Minneapolis, Minnesota and am in need of
a
Delorean for a video shoot. The church I attend in Edina, MN is doing a
week long event in the first week of November, our theme is "Back to the
Future".
In September we used a Delorean that was for sale at Sears Imported Auto
for a preview video, unfortunately that car has been sold. The new owner
is willing to let us use it but the scheduling is a bit difficult.
We need to do the filming next week (Oct. 20th - 25th) and we would like
to
have it at our finale event at the Minneapolis Convention Center on Sunday
Nov. 9th.
The filming will only take about an hour and we can compensate the owner
for gas and time.
If anyone is willing to help us out, please e-mail me at
projex(AT)bitstream.net
or call me. H - 612.870.9088 W - 612.673.9691
Thank you!
Jon

Subject: DML: Stainless Steel Frame?
Hello folks... Just thought I'd drop a line, as I've been a lurker for
quite some tyme and really haven't said much. I ran across this page
whilst surfing and wondered your impressions of it:
http://www.pearce-design.com/ ... They're a company out of Illinois
that sells a 100% stainless steel frame for the DMC-12. Has anyone made
this modification? Has anyone not made this modification after
considering it? Reasons? Any information you could provide would be
greatly appreciated. Thanks!
