ok well i went out to the truck right now and tested the voltage to the relay. i got 12 volts to the hot side (the one that has the rubber cover over it i assume) and then i turned the key and let the WTS light go and and tested for voltage on the other side of the relay and got nothing so i assume that the relay is bad. im guessing i should get 12 volts on the other sides since the relay should then be open correct?

In other words, the WTS light is not one of Ford's better ideas. That is why they should have put the WTS light in to the cold side of the GPR...then you know when it is on and you know when it is off.

Based on what you said, the glow plug relay is not closing. This is the problem but before you buy a new relay, make sure the relay is getting voltage to close.
Check for voltage on the small wire (thinking its the pink one). It energizes to close the relay. It is possible to have a good relay that is just not energizing.

Let me know if you don't have 12 V on the pink wire and we can go from there.
Since I am a day late, I'll bet you already got the relay anyhow.

yeah i went and tried to start the truck this morning didn't start on the first crank so got out an old 10mm wrench popped the hood and just crossed the relay terminals with the wrench and the relay started clicking here and there went back inside and truck fired right up. on the way to work stopped at the international dealer on the way to work and got a new relay. so got a quick project after work. One of the techs at the International Dealer told me tho that unpluging the connector that goes to that fuel warmer on the passenger side also helps a little with the cold start up. that sounded funny to me cause i thought that would help but he said it seems to be the otherway around. He worked in the BIG DIG project here in Boston as a deisel tech and all his company had at the time was 7.3 and if you are from around here you know the amount of trucks that worked in that 15 year project. and he swore by it, to unplug that connector. anyone heard of that helping them

im not to sure what exactly it is he said there is a bowl that fills with fuel and there is a warmer i gues that turns on when you key the key to let the glow plugs warm up. i think im going to have to go back and have him show me cause im still scratching my head after i spent my lunch break tryin to figure it out

ok looking through a manual i have and getting off the phone with that tech the fuel warmer that he was reffering to is at the bottom of the fuel filter bowl. but i still don't see how this is going to help in a cold morning start up?

i dont think this has anything to do with cold starts. if its not starting, maybe yes cause those elements take out a fuse when go bad, and will not start.
so by unpluging it will allow you to fire it up, after you replace PCM fuse.

got you that makes sense now. i will be leaving that alone i don't see how you would benifit in any way by unpluging that. unless i have the blown fuse issue from that element goign out.
Thanks Pete for the info
