A mpi system is high Pressure. If the pump is working it should have been spraying the fuel out of the hose. Hanes states that fuel pressure at idle should be 31psi with vacuum and 39psi without vacuum.

Hanes has a thorough looking test, but requires the vehicle to be started and running at idle.
Hanes states If pressure is not within specification. [31 with vacuum, 39 without vacuum] that one of the following problems exist.
