Re: [mk2-16v] Cis-e: possible stuck plunger? Waaaay too much fuel

2016-03-26 Thread denis.goldman 
Holland, many thanks.  I did check the 5th injector (cold start injector) and 
it was totally dry.  It might not even be working, but at least I can be sure 
it's not contributing to this problem.  

After dinner I worked up the guts to dive into the fuel distributor the 
Bentley's pictures aren't worth much, but a short paragraph of text was pretty 
precise for checking the plunger.  I pulled it out with quite a bit of 
resistance, cleaned it up a bit with qtips and fresh gas, and it went back 
together nicely.   Put all the intake pipes back and crossed my fingers as I 
turned the key.  A bit of a sputter, but then started up.  Ran rough for 15 
seconds and then settled in decently.  A ton of bluish smoke, presumably from 
the half of gallon of gas sitting in the downpipe and cat.  It will be 
interesting to see if my O2 sensor still works after this debacle.  

Honestly guys, I used to enjoy working on this car...but now with a fear of 
snapping brittle wires everytime I touch something, it is quickly losing it's 
fun.   Part of me wishes I could pull out all of the electronics and run 
megasquirt or even carbs, but I can't justify the investment.  

Thanks again

Something else just occurred to me. Does CIS-E have a cold start valve that
mounts into the intake plenum, like the Motronic system? If so, and it's
stuck open, that could flood all the cylinders.
Just a thought.

Re: [mk2-16v] Cis-e: possible stuck plunger? Waaaay too much fuel

2016-03-26 Thread Holland Phillips 
Since you've already established that there's fuel in all the cylinders,
that pretty much rules out a stuck injector. I'm more familiar with
Motronic injection, so I can't be very specific on where the problem lies.
Somewhere in the fuel system there must be a pressure regulator. Maybe
check the Bentley and see where it is. If it failed, and the fuel pressure
coming into the distributor is way high, it's possible that fuel is just
blowing right through the distributor straight to the injectors. One thing
you could try is pulling all the injectors at once, turn the ignition on,
and see if fuel squirts out of all the injectors simultaneously. That might
at least give you a better idea of what's going on. I was lucky and never
had problems with the fuel distributor, so I don't have much of an idea of
exactly how it works internally.
Just a couple of ideas.
