since the weather has got cold the truck has been hard to start and i noticed the wait to start light has not been coming on when trying to start truck so i replaced all glow plugs and made a new wiring harness and got a new gpr also wired it up the same way it was when i started and got no where so i googled some pics of the wiring picture one is the first way i tried rewiring and when i turn truck on it pops the 20 amp glow plug fuse so i found another picture which is picture 2 no fuses popped but selonoid clicks and then nothing please could someone send me a good wiring harness diagram which is correct for a 1994 f250 7 .3 idi turbo also if ya have any other info that may help me please respond thanks alot

 

OK so had to put new glow plug moduel in and now I seem to have glow plugs the only question I have is that after 15 seconds the Wait to start light goes out but I can hear the selinoid clicking for about 10 seconds???? Is that normal and if so when can I start the truck (After light goes out or clicking stops).
Hopefully some one can help Thanks

 

thats exactly what mine is doing my first idi did it too i always waited till the clicking stoped. idk what it will do if the motor is running and the gpr is trying to heat the glowplugs.

 

Well at least mine is not the only one that does it thank god!!!!!
