Hey guys...


Just rebuilt the injectors in my '83 300sd. It ran (very poorly) prior to doing this. The injectors got new nozzles and were balanced to 2000psi. Injectors function well on the test stand with a good spray pattern.


Installed them and have since ran 3 batteries dead trying to get it to fire.


I get a trickle of fuel out of the injector nuts when loose... but not the spray I was getting before. It's as if the injection pump is not building pressure.


It had the lines off for several days but stayed covered up.


I'm considering pulling the hard lines and elements out of the pump to see f they are sticking or something but I'm at a loss.


I know for a fact that it's got weak compression but I had it on the block heater for a few hours... engine warm... and it has fresh glow plugs. Its producing ZERO smoke from the tail pipe. It's as if it isn't getting any fuel at all to the cylinders.


Thoughts?
