Well I am finally forced to ask for specific advice. I have a D1105 in light tower that I just can't get going. I have followed many of the threads on here and concluded that my injector pump was not doing it's thing. I pulled the pump asked a service place to test it, was told they don't bother testing it, and I agreed to get it rebuilt.
I installed it today. Not happy.
A few details
I have no track record with this motor and never heard it run,
There is fuel in the tank
The electric fuel pump works and in the course of 10 seconds would pump 6 ozs. approx. not empirically tested but if you have a number of oz's it should pump let me know
the low pressure side cycles fuel like it should back to the tank
There is no white smoke coming from the exhaust
no smell of fuel
no fuel coming from the lines top of the lines when cracked or completely removed
EXCEPT a little tiny bit of fuel came out of the 3rd line
no fuel coming from the pump when all three lines are removed from the pump, whether at half throttle or at idle
Inside the body of the block where the pump sits, the linkage looks whole and springs are present and attached.
when spinning the crank all three lobs on the fuel camshaft turn.
when replacing the pump, took care to have the fuel shut off slide engage properly so that when it was bolted in the slider was in position for the fuel cutoff solenoid, it springs back with my finger as it should.
so what does everyone think...
I have not tested the glow plugs... no point, haven't got fuel yet,
nor did I test for compression.. no point haven't got fuel yet
what simple thing am I missing?
Do I have to prime the injector pump?
the oil looks ok, doesn't smell like diesel, tastes like oil
