Hi all,
First off, thank you for your continued support.
I have had a "no start" situation for months now and I am really about to quit. I keep saying this, and interestingly enough, I keep at it. Insanity must be in my blood

I have one question to ask: How is it possible to have no control over the fuel pressure? Specifically, I am attempting to set the CIS mixture and I have discovered that no matter how many turns in or out I go with the 3mm set screw, the fuel pressure/volume out of the injectors is the same.
Am I missing something?
This all ties into my main theory that I am getting too much fuel into the cylinders and it continues to saturate the plugs.
Again, what am I missing?
My uncle had been helping me in the past, but he is so busy these days that I am on my own now and I am flailing. Please help.
Thanks!

Possibly the plunger within the fuel distributor is gummed up or stuck in position. Try taking out the three bolts the hold the distributor to the air flow meter to see if the plunger moves freely.

cheers

Thank you for the reply. I should have added that the plunger and fuel regulator were checked and were deemed operational. No sticking and the o-ring is new on the regulator plunger.
