Fuel pump relay and cooling fan relay
Ford Fuel pump relay and Ford Cooling Fan relay troubleshooting is as follows:------
Here is the fuse location (fuse 13) and also the constant control relay module location.The Ford fuel pump relay is located in this module.
If your cooling fan is running(this is the default,if you disconnected the PCM and then turn the key to the run position the cooling fan will run) and your OBD2 scan tool is not linking up your PCM is not powering up.
When it is acting up check and see if you have power on the red wires on pin 71 and 97 at the PCM.This gets its power from the PCM relay on the ICRM(intergrated control relay module).
Here is a copy of the wiring schematic to help you.
The relay control module is the one located on the radiator support that houses the relays for the PCM,Fuel Pump,AC,Cooling fans.
Here is a pic of the connector at the relay module.
