Someone told me recently that a modern fuel injected Jeep with
electric fuel pump cannot be push started if it has no battery in it.
Is this true?
Earle Horton - 30 Mar 2007 16:17 GMT
This is true of any "modern" vehicle with an alternator based charging
system, made since 1960 or so.  Bill, Matt or Mike might be old enough to
give the exact year.

Bummer!  And here I was thinking the '95 would start like the '43.

Earle, you are out of phase with the rest of the world by an hour ahead.
 Either your PC clock is off or the time zone is.

I keep reading replies to your posts before I see your posts...

My PC is spot on.  Maybe there is a bug in the "solution" that Microsoft
distributed for the problem of our goverment screwing with Daylight Savings
Time.  It is 10:18 Mountain Daylight Time right now in Albuquerque.

Your post just showed up at 1:21 and it is still only 1:00 here.

How is your time zone?

Microsoft distributed an application to allow us to manually edit the
characteristics of the time zone, to "fix" the problems created when our
government changed the start and end dates.  I have set MDT to start the
second Sunday of March and end the first Sunday of November.  We are in
GMT - 07:00.

Earl, -7 is MST. We are on MDT, at least in SE Colo., now.  The headers show
that the qwest nntp server is getting your post one hour after you post it.

There is a gotcha in the Windows DST logic.  If you applied the fixes while
the computer date was prior to the changeover, all went well. If the
computer date was AFTER the changeover date when the fix was applied, the
internal switches were never applied because the clock correction only
occurs only on two specific cases: date/time rollover ON the changeover
date or if the last update to the system clock occurred BEFORE the
changeover and the next update is AFTER the changeover.  I had problems
with all the clocks on the church computers because I didn't run the
updates until after the new switch date.

Simple way to do it: make sure the hotfix for time is applied.  Reboot and
either use the BIOS to set the date to BEFORE the time change.  Boot.  If
you have the network time sync running, it will fix the date and time
catching the DST crap up as it does.  If you don't use the network time
sync, just change the date to the current date and it should make the time
change for you and get you in sync.  That's what it should do.  What MS
thinks it should do is an open question  I just noted that the wife's
laptop is all messed up and it was running with the fixes!  XP Media Ed.
Let us know how you make out - I may need some MS advice since I almost
never run it.

Will,

Your post shows up here as having been posted at 10:13 PM, but I think you
actually posted it at 11:13 PM.

Heh.

Uh huh.  Reading the full headers, my post comes back here with:
Date:   Fri, 30 Mar 2007 23:13:10 -0600

Yours omes in as:
Date:   Fri, 30 Mar 2007 23:28:07 -0700

The -0600 is the UTC offset my computer attaches, the -0700 is attached by
yours uses for your offset.  Now, I know Sliverton is in a world of it's
own but we should at least be in the same time zone!  Or has one of us been
listening to Coast-to-Coast radio too long? (Dang, I miss Art Bell on these
late nights!)

I think this fixes it.  So you think this is going to stay fixed?

Search www.durangoherald.com for Silverton.  Or look at this link.

Got the timezone right - now if you would just set your clock <g>...

Earle, I don't know how all the pieces in Winxx work, but all the library
routines I use for localtime() rely on an environment variable
called %TIMEZONE% or %TZ%, depending on which OS I'm compiling for.  What
that essentially means is that the settings are not propogated until after
a reboot since the timezone setting is a global environment variable whih
means that it is read in on boot and never changes until a reboot.  That's
why hanging a timezone setting results in a change in the display only -
the PC clock is never altered - period.  There is a setting in Windows -
been there sine 3.51, that activates a network sync for the hardware clock
to a remote time standard like NIST Boulder.  That's the only way I can
keep all my machines synced.

Hi Earle,
   What I find interesting is the day to night light line runs diagonally
across the U.S.of A. so as to make day time at ten P.M. in Utah, four
hundred miles north east of me dark a eight P.M. Summer months:

Well, you are an hour ahead of yourself, just look at the newsgroup time
 tag on this post.  It says 2:20 here and it is only 1:50 still.  Your
local one should show the time off too with this post of mine showing a
half hour earlier than yours....

As you know, Microsoft went all to hell after I quit working for them.  They
sucked while I was there, but now they have gone all to hell.  A temporary
fix is that I am going to spend two days at my other house now, and if what
Will says is right, that computer is OK.

Hi Earle,
   True, it'll pop the diode from any car with an alternator. And fifties
was the last of the rear pump automatic, so they're added to the list.

Yes. Same for having a dead battery in there, you are screwed.

Even in my old 86 it won't start with a push and no battery because the
alternator won't turn on with no power.  It has to have a few volts in
there to get the alternator field active.  The new ones have to turn on
a computer to turn on the alternator.

Push starting with no battery went out with the generator vehicles and
maybe some first generation alternators.  They all need batteries of
some sort in there now.

Thanks for the replies.  I'll keep this in mind now, not be so
confident about being able to start.
