First I would like to say this is a pretty great forum, and thanks.
I'm having trouble starting a D17, a 1950's model I believe.
I cleaned out the fuel valve underneath the tank and am getting good fuel flow up to the injector pump. However when cranking I do not get any flow from the pump to the heads. I've opened the bolts on the outflow side of the pump, to check for flow, without any luck. I usually crank in 10-15 second intervals.
Do you guys have any suggestions as what other things to check for before chalking it up to a rebuild?
