Yep, to the best of my knowledge, the fuel flow is as you described.
Do you have a fuel pressure guage? When I was having stalling and
failure to start problems with my '96, a Dodge dealer thought it was the
fuel module and replaced it. The problem was actually a loose connection
in the wiring harness. Anyway, during the course of trying to diagnose my
problem, I installed a fuel pressure gauge in my truck. It sounds to me
like the problem probably isn't the fuel module in your case, but being
able to monitor a fuel pressure gauge is helpful. (When my truck died
with full pressure at the fuel rail, I knew darn well it wasn't the
pump.) Anyway, maybe you don't want to bother with it, but if so, its
only about $40 and pretty easy to install. (I used an Intellitronix
digital fuel pressure gauge; that way the only thing you have to run
inside the cab are electrical wires.)
