Its whatever is feeding the relay to tell it to click on or off.
The fuel pump relay module is energized by the ECM which in turn
operates the fuel pump to pressurize the fuel system.

Any suggestions to a quick fix to get the truck home?

i replaced fuel pump and wiring about 8 months ago. im getting plenty pressure and sometimes the clicking will slow when it does the truck will crank. its just running super rich. the motor is rebuilt with less than 5k miles. when i pulled motor and rebuilt i replaced a bunch of the really "great land rover wiring." whatever relay this is, it seems to be controlled by fuel pressure or maybe rpm's via fuel injector pulse or visa versa......hope all this makes sense.

yes its the one clicking. I can pop the hood and pull the injector fuse and the clicking stops. while it is clicking you can go to the back of the truck and put your hand on fuel pump and feel it pulsing with the clicking. I have a feeling if i bypass the relay then the pump will just stay on. Im thinking that its some sort of fuel pressure switch or something like that causing the issue??? its not the relay itself it is fine. Its whatever is feeding the relay to tell it to click on or off. Truck ran fine on the way to work. got in it after a few hours to grab lunch and it started the clicking, hit the rocker panel with my fist clicking stopped and truck fired right up. go to burger king kill the truck go in and eat come back out and as soon as i hit the ignition switch it goes to clicking. You can feel the injectors pulsating when it clicks. so its the relay that controls them.......i dont know im lost lol

i have pressure shooting a three foot stream from my fuel rail. while relay is clicking these things are happening, fuel pump cycles with clicking, injectors open and close with clicking, evap canister opens and shuts.
sometimes clicking will slow. when this happens the truck will crank but just floods itself out. truck has plenty of fuel in tank.

No sparky is coil so check those connections and also the pick-up amps on these motors don't like heat a whole lot and they fail. Cap and rotor must be Lucas otherwise you'll be chasing your problem for a long time. There is a really good troubleshooting section in the Rave on the distributor system, try it out. Doesn't always catch the fault but it sure helps rule them out.
