I think I found the problem, now what? (WAS: New member with bad problem)

Today I got the fitting for the new fuel pump and it now fits very well.

I followed the instructions which many suggested.

Removed an injector from the car and put it into a bottle.
Put the car in the "On" position.
Turned on fuel pump manually.
Tried to move the sensor plate up and down.

The plate which moved freely and easily before got VERY stiff. It would come
up about 2 mm without a problem but then got too stiff for me to lift with
my fingers. At that point I saw the injector activate. The spray pattern was
like in those STP TV commercials, "this is what a dirty injector looks
like". Ether way, there was fuel coming out of it so that's all I care about
at this point. Since I have the air box lose right now I put my hand under
the plate to see just how stiff it is. With some pressure I was able to lift
it. The flow went up a little bit but as the plate got higher (almost to the
top of its travel) the flow stopped completely. I lowered the plate down
(there was still considerable force pushing it down) and the flow did not
resume. This explains the problems I have been having 100%. The engine
idling more or less ok but once I pushed the gas it would die even if I
would let go soon after. Does it also explain why my pump fired?

Ether way I turned off the car (put the key in the "off" position, the car
was never "running") and tuned off the pump. After waiting about a minute or
so I felt the sensor plate again. It was a bit softer than before but still
very stiff. I decided to experiment and began to remove the thing on the
front of the fuel distributor (it is referred to by many names, I think its
a pressure controller of some sort) that is held in by 2 flat-head screws
and has a 2-wire harness going to it. Fuel came spraying out like never
before! The plate became free moving again... I screwed the gray thing back
on and tried to start the car. It sputtered a few times but did not want to
go...


Ok, Huw, others who know this system. Tell me what to do. I will do it. I
*THINK* the problem is with that gray 2-bolt part not controling the
pressure right. There is a 2 wire connection going to it. How do I test it?
What is my problem?

Thanks,
