Yes, it could be the starter solenoid. Other possiblites include a bad
battery, dirty connections between the starter and battery, and a worn
out starter. You really need to get a voltmeter on the solenoid and
see what is going on.

Get your battery load tested. I have seen batteries fail in such a
manner. It seems like there is a bad internal connection. Also check
all of the "big" connections between the battery and the starter. Next
time it won't start jump the battery with a known good one. Take one
of the new battery jump start packs with you on the Fall Tour!

Hey all!

Just wanted to let you know that I'm moving to a new domain name for 
DART.  The new site will be, and the old 
site is no longer working.  You may continue to contact me at for any questions or orders for the INDIGLO Dash

Subject: Re: Bypass? No...I think my car need therapy!

Practice your troubleshooting techniques now, BEFORE Fall Foliage:

Remember -- there's a reason behind everything (and also remember:
every problem has a solution).

Start by jumping RPM relay. Insert a jumper between brown wire and
white/purple. This should cause pump to spin. If it doesn't, you've
narrowed problem to pump power supply or ground. Test for power at
brown wire (fuse 7 could be blown or not making contact). Test for
ground at pump itself.

If pump spins, test for resistance on air sensor plate. Plate should
not be totally floppy, and you should hear fuel literally squeak past
piston when raised. If air sensor plate behaves abnormally you're
probably not getting enough pressure to crack injectors. Could be bad
regulator in fuel distributor. If check valve on pump is bad system
could be full of air. Let pump spin for several minutes and see if
system pressurizes.

Make sure idle speed motor hasn't stuck closed. Use accelerator pedal
to open throttle plates. Don't bother pumping pedal -- no accelerator
pump. Engine could be slightly flooded from testing air sensor plate
above (you'll know if car finally starts and emits a cloud of white

Test for ignition spark. Is a stretch, but center terminal on ignition
distributor is reachable behind/under fuel distributor. Pull coil
wire, push boot back to expose metal contacts, and place very near but
not touching the block. As engine turns over you should see high
voltage spark jump to block. Spark should be blueish or white, not
orange (low voltage). If you don't have a spark, start checking
connections from coil towards ballast resistors. White wire is primary
ignition voltage -- should be 8-10 volts. If you have a spark but is
weak problem could be starting relay -- run temporary wire from jump
start post to positive side of coil.

Note spark test can also be performed with a timing light (just look
for bulb to flash) or an ignition probe.

If you've got fuel and spark but car still won't start, check for
final delivery at the head. I usually use cylinder #3 because it's
easiest to access. Pop injector out of head, place in a coke bottle or
some such, and perform air sensor plate test. You should see injector
spray. Likewise pull spark plug wire, ground next to block (terminal
recessed pretty deep -- may have to extend beyond boot with a
screwdriver), and look for spark. Or test with light/probe.

Make sure you don't have a catastrophic vacuum leak. Supply line to
idle speed motor is 3/4" -- quite a lot of unmetered air if it's come
loose. Make sure cold start tube still seated firmly on manifold (is
visible between cylinders #1 and #2.

Make sure spark advance diaphragm isn't getting vacuum while starting

Since car misbehaves cold and hot, doesn't seem to be classic "hot
start problem," but is good to practice -- plug warm up regulator
(grey plug) into cold start tube. This will cause cold start valve to
spray extra fuel into engine no matter its temperature. If engine
starts, quickly disconnect cold start tube before engine floods.

While you're practicing -- try using a jumper to turn on headlights
("dipped beam") at relay socket. Is row closest to passenger seat,
relay closest to center of car. Locate two parallel terminals rotated
90 degress from other three -- line in is closest to outside of
socket. Line out is directly opposite on other side of socket (middle
of 3 remaining terminals). If you jump line in to line out, headlights
should come on. This will get you around a broken dash switch.

Try using same jumper to make cooling fans spin. First, pull
connectors off otterstat and jump together. Fans should spin as soon
as car energized (will get you around a broken otterstat). If fans
don't spin, leave otterstat jumped and jump relay just like headlights
above (same row, second from outside end). If fans STILL don't come on
you may have problems with whatever's plugged into fan fail socket
(next to fan relay), circuit breaker, or fans themselves.

Car has two mombo relays next to RPM relay -- Main and Accessory. Are
identical. Since car will run with main relay only, is possible to
swap with accessory if main relay fails on the road. Accessory
adjacent to RPM relay.

Should be enough to keep you busy for a while. Is best to practice
things like this BEFORE they're needed. Most car problems can be 
overcome temporarily.

Good call David. Since it only does it on the highest speed tt's got to be
the 4th speed relay. I always forget about those things.

Subject: Tires

Tires seem to always be a popular subject on the list. There's a web site
that, while it is a commercial site for selling tires, has a wealth of information about 
wheels and tires. There's even a caculator that will compare dimensional specifics between varous tire sizes.

Subject: amazing vacuum discovery


As many of you know, my car has been plagued with slight running problems 
ever since i got it.  part by part, tweak by tweak i've gotten the car WAY better 
and thru the whole summer it has run flawlessly with only two problems - 
lower end of the spectrum gas milage and i have always felt my car ran rich even 
though it doesn't show other symptoms.  my exhaust has always smelled like 
unburnt gasoline.

well yesterday i was doing some cleaning and i knocked the vacuum hose that 
goes from the thermal control valve to the middle orifice on the vacuum advance 
canistor/solnoid behind the fuel distributor.  the hose felt a little loose i 
cut a bit off of it to give some fresh hose to the fitting.  lo and behold, 
inside the part i cut off there was a little BALL BEARING wedged into the hose, 
apparently to correct some problem by cutting off vacuum years ago that a 
previous owner/mechanic did.  great......

now my car idles at around 950 (used to be 775) and when it is hot the idle 
sounds kind of squirrelly.  this is terrible because i think i have been 
working around this BS for years and now is EVERYTHING out of wack?

this summer i have:
replaced advance solenoid/canister
had CO professionally tuned by a ferrari restoration shop
had timing adjusted
adjusted throttle linkage and all that

actually everything on my car was more or less perfect until i found this 
'problem' and 'corrected it'.  i expect to have to get the timing adjusted, but 
what else will have to be done now?  the book says timing should be checked at 
775 rpm.  i am a couple hundred higher than that.  will that make a 
difference? how do i get the idle back down again?  will my CO have to be adjusted again 
(i drove 300 miles to get it done)?

any ideas on how to calm things down again are much appreciated!!
