If you think you've got a stuck injector I'd pull the plugs to clear the pistons. Otherwise, if it fires you could hydrolock the cylinder and break the crank and all of that.

Sure sounds like it though. I have the same pump and don't remember what the pressure did.

But I will caution you that this pump is big enough that it should still hold pressure while running even if you had EIGHT injectors locked up. I was close to 100% duty cycle on my 85# and the pump was still happy. So in other words one stuck injector can't really be responsible for operating pressure problems.
