Make sure the connections on the positive battery terminal are
healthy--high resistance there will greatly affect glow plug
performance.
Check over all those connections.
Test each glow plug with an ohmmeter. Disconnect each one, and test
the resistance between the stud and a healthy ground point on the
head. Each glow plug should be less than 1 ohm. An open circuit
indicates a bad plug.
I have tried Autolite glow plugs, but somehow they don't seem to do
as good as the original Bosch ones in really cool weather... I can't
explain why.
