I wouldn't sweat that Nick- you have power to the plugs.
10ish volts is correct when the plugs are in the circuit- each plug
causes a small voltage drop of nearly a half volt in the circuit, so 10
is right. I understand what you are chasing- a connection with high
resistance, but remember, with this amount of current, any resistance on
any connection would quickly make a resistive connection VERY apparent-
it would be smoking, melting plastic on the relay holder for instance.
You just can't block that kind of current and not have A LOT of heat
generated VERY quickly.
If you want a definitive test, pull an injector out and observe the plug
tip.
I have ran across an intermittent fuse on the firewall in the past, that
was a fun deal to find, and the half dead fuse lasted forever until I
touched it.
Otherwise it sounds like your car is functioning normally re: the cold
start lever etc.
I really like a permanent indicator light wired to the glow plug bus
bar. takes away a lot of guessing if it decides to not start right.
