So it is dropping to a low of 10 psi. It is a head scratcher because it sure sounds like a fuel pump resistor problem less the pressure going back up when you pump the accelerator. Providing that all wiring is confirmed good and all components in the fuel pump circuits are OK about all I can think of is the PCM module itself. It does control the switching. Also, you might consider checking wiring between the PCM and back to the two relays in the engine compartment fuse box. Is the PCM stock and have you ever had any work done on it?
