just some random thoughts, Matt sent me in here and I thought I'd throw in my somewhat experienced 2 cents...
30psi is probably due to fuel washing down the cylinder walls.
if you are on the stock tune using bigger injectors, that is your problem.
The Focus does not have a fuel pressure regulator. There is the pulse damper and also the delta pressure sensor. The pressure sensor uses the vac line to tell the difference (delta) between the rail side and manifold side of the injectors. Then the ECU uses this to tell the fuel pump how much pressure to put in the rail to achieve 40psi across the injectors.
make sure your crank position sensor is plugged in.
have you checked spark yet?
i have some more random thoughts but answer those first and we'll go from there.

Not on this list? Almost certainly crap.
