Good morning Guys and Gals,
I've been trying to breathe some life into my dad's old 560SL. It has been sitting about 5-10 years in southern Cal outside. The engine has good spark and runs if I use starting fluid.

What I've done so far is:

Replace fuel relay
Drain old fuel from tank.
Exit hose rotten, so replaced
new fuel pumps (2)
new fuel filter
replaced hose clamps and some lines on fuel pump assembly
checked for leaks

Now I have good fuel pressure to the fuel distributor, but that's as far as the fuel goes. The injector lines remain dry of fuel.
What is my next step before removing and trying to clean rebuild the fuel distributor?

Thanks for your help
Jeff
