The power/signal is not getting to the fuel pump. I have been unable to find a full wiring diagram to trace the wires with our ripping apart the car. Can you tell me what sensors trigger the fuel pump and or relay.

To get the car home I ran direct power from the battery to the pump, the car started ran fine, no codes.

Since the car runs with direct power to the pump, I am ASSuming the Crankshaft Position Sensor and the Camshaft Position Sensors are ok. The only think left is the Oil Pressure Switch, MAS, TPS I think.

Any info will be greatly appreciated. - Mike


I have checked and believe they following are ok.

1) fuse and relay [clicks] (OK)
2) Pulled the relay and swapped it with a fan relay (NO CHANGE)
3) Pulled the Relay and put a test probe on 85 (?) And the light goes on for ~2sec then off (Prime)
4) ground test (battery to pump) (OK)
5) inertia switch [ Shake test and reset ] (OK)
6) continuity test from inertia switch (pink/black wire) to pump (OK)
7) pressure check at fuel rail ~ 61psi (steady run-time)
8) added 2 gallons fresh gas w/heat
9) Check the oil and its full.
FYI: Ignition switch was replaced last year.

Jump pins 30 and 87 together in the relay's socket, then see if the pump is running. If it isn't, measure the voltage on pin 30. Check out the diagrams (Below). Please let us know what you find.
