How much fuel pressure at injectors?

Hey Guys,

I'm trying to diagnose a no-start with my 300E. Today it quit on me while running errands; prior to this, engine ran and idled flawlessly. I've checked spark, OVP fuses, and fuel pumps (2 -- I think both are turning but can't tell for sure)

I busted open bolt at pressure regulator and got a nice spray, then re-primed and tried an injector... and nothing ... just a couple of drops of fuel came out. Tried a couple more with same results.

Is this normal? Should I get a "squirt" when I break open a fuel injector? I tried some engine starter in the intake, to no avail. Engine cranks fine ... just won't catch at all.

Any help is appreciated
