1987 300SDL with 230,000 miles of which 25,000 miles I put on myself.
I am having a "fuel injection problem".

My problem is that I can not get the injection pressure to pop the injector and get the fuel into the cylinder.
I have the injection pump timed at 15 degrees after top dead center with the "vee" right in the middle of the governor's hole.
I even went further and did the drip test, using an injector line and at 24 degrees before top dead center, the fuel sat there and dripped about 1 drop per second for at least 35 minutes and would have continued if I had not turned the engine using the crankshaft bolt.
I've tried loosing the injector seal and measured the amount of fuel pumped using vinyl tubes attached to each injection pump fuel outlet.
The fuel would flow as much as I wanted it to.
To gushing out to fill the vinyl tubes quickly, (a few tries of turning the switch), to hardly any fuel being pumped, based on how tight the injection pump fuel outlets are tightened.
The fuel would pump through the injection pump, but would not build up enough fuel pressure to activate the fuel injector to inject the fuel.
To test to see if fuel was being ejected into the cylinder, I used a fuel line and attached an injector and turned over the starter and look for fuel injection.
And though fuel would pump, I've had no success getting the fuel to build up enough pressure to inject the fuel.
Can anyone help me solve this problem?

Thanks in Advance
