Both the fuel pump relay and the Injector Driver Module, IDM, are in the battery junction box under the hood. The IDM itself is on the left side of the inner fenderwell boltted to the upper frame rail.
See if the clicking is coming from one of them.
Then have the trouble codes pulled. Any Advance Atuo or Auto Zone will do this for free.
When you get them, come back to us and we will go from there.
