Info I have at the moment Chiltons for all models 95 the PCM shows no involvment with the fuel system (except vapor purge). 96-97 PCM shows pins 80B/BL & 40PK/B go to Fuel pump relay. 98-99 pins 54 B/BL & 40 V/B goes to fuel pump module and 62 PK/B goes to fuel tank pressure sensor (Mitchell's says it's transducer and gets involved with ATX Park position, MTX with clutch switch and both go back to PCM (Gist only). 96-99 pin 40 monitors the voltage to the fuel pump, of course the inertia switch is in series with 95-99 and the fuel pump. ALL is 2.5l info Zetec similiar.
At the fuel pump Power: 95-97 should be battery voltage.
Fuse 15a no number? (got to love Chilton's?) to inertia sw and on to fuel pump all PK/O wires Ground at fuel area. (Check for clean ground connections)
98-99 Fuel Pump relay/Fuse f14 15a V/O to inertia sw V/O to fuel pump and ground at fuel pump area. My 98 after just two years was very rusty. I cleaned up and coated w/ Krylon's "Crystal Clear Acrylic Coating" 1301. I use on all grounds, power even battery connectors and all my ham radio outside grounds and antennas. Does good job slowing corrosion. Nil.
Whew! Paul
Need any explains don't hesitate I'll do my best.
Chilton's one note 35-40 psi. under normal conditions and 30 psi idle or high vacuum.
I have access to Mitchell's through my local library also Alex Peper OBD II guru his first was Mitchell's for what it's worth!
