Subject:      Fuel injector question - non starting
Content-Type: text/plain; charset=ISO-8859-1

Dear group,

After reading the dire consequences about not replacing 20 + year old fuel
lines as well as looking at the dreadful pictures, I wisely succumbed.
Additionally, I wanted to change my rusty air distribution system which
included a very scaly manifold.  When pulling everything apart, I also ended
up replacing 4 corroded fuel injectors with a respectable set of used ones
complete with new rubber seats.  They all "clicked" when I tried them out at
the Bugshop.

With everything put back in place and looking much better - I tried starting
my van and...it wouldn't start.  Basically it turns over but won't catch or
idle or even sputter and cough.

I have a 1986 Digifant 2.1 L motor.

Here are some questions.

Question 1:  With the ignition on should the control valve for the idle
stabilizer vibrate and hum?  Mine does and I figure this is correct.

Question 2:  With *all the injectors* unplugged from the harness and the
ignition on - when using a test light, only one of the injection inputs
 from the harness lights up for each connector.    Can someone tell me which
is the corresponding male end on the injector itself - in other words which
injector prong requires the hot end from the harness plug?  When looking at
the ends or prongs at the two injectors for cylinders 3 & 4  should the
power go to the left or right prong for each injector - left for the intent
of this orientation being cylinder 3 as left to cylinder 4 and cylinder 2 as
left to cylinder 1 - or left being toward the front of the van and right
toward the rear.

Things I've checked:

   - I believe I'm getting fuel as I've pulled off the fuel line at the
   plastic distributor rail with fuel spilling.  As well, the injectors are wet
   from fuel from when I pulled them out from the manifold.
   - I believe all plugs and hoses are on and in place - I made some
   diagrams to make sure everything is correct -
   - I removed the throttle housing when doing my initial work and placed it
   back onto a refurbished intake distributor.  I did not tamper or touch the
   throttle valve switch nor has the idle adjusting screw been touched.
   - The throttle cable was reinstalled close to its original position prior
   to the disassembly.

I noticed that the Bentley on page 24.47 for the digifant shows the fuel
rail or fuel distributor as backwards as how my van was configured - The
flanged end should be installed toward the front of the bus and the rounded
end toward the rear of the van.  I also used Ben's good photo essay about
 fuel line replacement and his photos also confirm the Bentley has the fuel
rails backwards.  Mind you, this could be old news.

Thanks,

Bruce
