so.....
still dealing with the startup issue after shutdown.
I did change from the overboost valve to a giant fuel selector valve you can actually feel activating when you turn the key. There is no question its fully turning, and the way the vehicle operates is the same.
There is no reason this arrangement should not work properly, with the key on, the vac to injection pump is fully open to atmosphere, yet im still having issues starting back up right after running. Ive tested the line, and no residual vac in the line, yet still the hard to restart
Im wondering if maybe my issue is the injection pump shutoff valve itself? Could it be sluggish or sticky and not moving back fully? is there anything that could prevent diaphram from releasing fully?
It really acts like the line is still seeing engine vac, but its not at all. Instant bleed off. This is a weird issue
Here is the change in vac shutoff valves-
first version-
version 2 over the top solution-
