More updates if anyone can help? I open the high pressure pipe from the cut off going to the regulator and with everything else connected (Don't try this at home children) gave the key a quick turn and there is full pressure there for sure! I still cannot get any pressure reading at the regulator test port. My digital test pressure tester is new and I checked it on my van wheel and compressor and seems to work fine. My adaptor at the reg is just a treaded on one end brass pipe and I have a valve from a car rim shoved up on it. I used this adaptor before testing other equipment and it seems to work well. Just to be sure the valve is opening I cut of the first 1mm off it so it will be sure to open. Long story short I have full high pressure going into a brand new reg but I am not getting the results at the test port. The only other thing I did since is I found a restrictor inside a red plastic pipe which runs from air intake and enters nears the base of the throttle body. This restrictor did seem to be a bit blocked but after clearing it the engine will now no longer run it just starts and instantly stops. Any ideas welcome.
