Front one is fuel pump. Clicking is good.

Postin' from teh Galaxy
 
They shouldnt bbe clicking while im driving though right?? First time it would start cutting out i could hear them clicking as it was cutting out when i was driving... loss of power from somewhere...
 
Not necessarily loss of power at all.
Could be a loose ground.

Check them all, they are on your inner front fenders and one on the radiator support.
Be sure to verify the small one from the Bat - terminal.

No, they should not be clicking.

What you should know is that when the PCM relay engages, it routes power from its closed contacts to engage the relay coil of the Fuel Pump relay. That makes it important for you to determine WHICH relay is clicking. If it is BOTH, concentrate on why the PCM relay is clicking and don't worry about the fuel pump relay at all.

Yea i found a losse ground and fixed it.. now i dont have any clicking of the relays.. now just cutting out all the time... cuts out for a few seconds then when u hammer the thorttle it goes away.. then back to cruising comes back..
 
Are both relays still the Ford factory type or are they aftermarket with the circuits imprinted on top? The fuel pump relay will have a diode between 1 and 2 circuits to keep from back feeding.
