Water cooled Vanagons  do not have cold start valves. If fuel was not
coming out of the test tee, then there is no fuel pressure. Need to
determine if the pump is running. It can be heard or felt if it is
working. Is it getting power? If not, then fuel pump relay or wiring
needs to be checked.

Hi Jeff,

I would suggest you disconnect a fuel line at the cold start injector
and stick it into a gas can. Turn the ignition key and see if gas
flows out.  Be careful, there is a definite risk of fire in this
procedure.

If fuel does not flow out when the ignition is turned over you have a
bad fuel pump.

If yes, then you may have a bad ignition circuit. The injectors are
triggered by the pulse in voltage at the coil caused when the spark
plugs are fired. No spark can also mean that the injectors won't
fire. Check for spark at the plugs and let us know what you get.

You might also want to charge your battery. 10.5V might not be enough
to awaken the ECU.

Happy trails,
