also, if you were checking fuel flows and got a few seconds of fuel followed by a dribble, were you lifting the sensor plate? As I understand it, you'll only get a burst of fuel from the pump turning the key, and unless the sensor plate goes up, fuel flow stops.

Or am I mistaken or misread stuff? The two times my system has been misbehaving, first it was fuel pressures off, second was a vacuum leak and sticking throttle cable.

Movement of the sensor plate causes the pump to run. Also,
if the sensor plate connector is removed, the pump runs all the
time, i.e. the fuel relay is de-energized (87 & 30 are normally
opened by the sensor plate contacts) causing 87 & 30 to make
contact & pump runs.

if you had any of the rust in the system I would recomend that you take the WUR out and clean it. The inlet side of the WUR has a stack of tiny screens that can plug easily. I remove them with a small pic and then clean all the screens with carb cleaner. You would be surprised how much stuff can be lodged in between all those screens. This is easy and you don't even have to take the WUR apart.

Ah Hah! I was going to suggest two things: Fuel pressure check, and blowing rust out of the lines. Now that we know this is almost certainly a rust problem, be aware that CIS systems are highly sensitive to fuel contamination problems. I'd strongly suggest you remove all components that pass gas (WUR, Accumulator, etc.) and rinse them out thoroughly. While the lines are disconnected at both ends (partly because these components have been removed), blow air through all the lines. Drain the tank and clean the screen.

If you allow rust to continue to flow through the system, more CIS components will fail.

NoStatic,
Yes the sensor plate was raised just a little but enough. Since I don't know what is in the accumulator yet, (I'm going to cut it open and look) I am unsure if this was the total cause. I have other problems, like maybe still an intake leak or vaccum leak to find and fix first. Then off to a well equiped shop for (hopefully) tweaking. Question: how would an exhaust leak express sitself in CIS misbehavior?? There is a small one at the right side crossover pipe. Also, how does the fuel return work, ie where is the line? What symptoms can this show if it blocked or not draining properly? Thanks to all for the comments. I don't know about you but I am absorbing information at a rapid clip!

I assume you are driving it?
The fuel leak (since it's small) most likely is as simple as the 4" long (low pressure) hose that goes from the fuel tank to the fuel pump. It's regular hose with hose clamps. I had to replace mine and I have some left over (I think, I'll check) This is also a good way to drain the tank while your doing it. I've done it with the tank full. Someone can confirm that there is a drain with a screen on it. that also can /should be cleaned.
You can check the other areas that were mentioned.

Again if your driving it you can stop by my house and I will give you a tour of the CIS Parts, I'll lend you the books and the CIS gauges.
The gauge only takes about 5 min to hook up ans will tell you most of the story.
I have a used WUR you can try as well.
PM me or I thnk you have my e-mail.

The accumulator's function is to dampen system fuel pressure and to keep fuel pressure up for a while after the engine is shut off. That way you will already have pressure the next time you jump in the car and start it. It shoul hold about 1.3 bar after 10 minutes and 1.1 for 20 min.
(That's the 81-83 spec. but it's probably the same or close for the 79.)
The 79 Accumulator is bigger than the 81. I believe inside you will find a diaphram and springs. (Maybe more accumulate rust.) Fuel passes thru this just after the filter and then to the fuel distributer. The fuel distributer feeds the cold start valve, the 6 injectors. It bleads excess system pressure back to the tank and supplies the control pressure regulator which bleads excess control pressure back to the tank.

Do you have a pop off valve?

The accumulator acts, as mentioned, to dampen system pressure, i.e. also
under hard accel where fuel demand is greatest.
