I am going to have to do this as I am in need of another project. AFFORDABLE one too, due to XMAS

happy holidays!

Are you sure that you are not hearing the pump instead?

Relay is brand new, replaced the beginning of this year. The noise is an "electrical" noise is the best I can explain it.
I have touchy ears, though.

Absolutely nothing to apologize about, Ron. I had done it but never posted about it. PROPS to WMRiceman!
XMAS has slowed a lot of things down, except the amount of outgoing money...

Positive, cause I can hear when the pump shuts off, The GPR is on much longer. Now with the light, I kinda have personal proof which one I'm hearing.

ok so i hooked up my led today and nothing, no light. I tested the two small connectors and they have power. The main from the bat also had power. Does anyone know the purpose of these signals because they were hot when the truck was hot and cold. I have tried to find the schematics but have had no luck. My truck is a 2000 CA model, so i only have one gpr. I think with the two small wires hot it should be triggering but why are they not turning off? Also i went to pep boys and picked up a relay which didnt work either so im thinking ill just go to ford, or i have a different problem.

Think i found my problem. The purple small wire is a computer controlled ground which is the trigger for the relay. From other research online i found that many of the ts chips were not designed for the ca pcm. I removed the chip and will see if the relay will trip when cold in the morning. If it still doesnt fire, do i need to buy a gpr controller CA only or a pcm?

I ran the red wire on the LED to the post on the GPR that feeds the GP's, ran the black wire to the ground on the battery.

Gtlegacy your CA only truck is different than the rest of the fleet. We have two relays where your one is and you have a special controller for your glow plugs.
I cannot offer any advice on how to fix it, but it sounds like you are on the right track.

TurtleRacing says the voltage from the GPR to the glow plugs stays on even though the engine is at operating temp. So, does this voltage continue to operate the glow plugs or does the PCM somehow interrupt the voltage between the GPR and the glow plug when the engine is at operating temp.?
Thanks,
