no power to glowplugs

[01flatbed]

after pulling my glowplugs out, i realized i wasnt getting power to them. Besides checking the relay, are there spots prone to wire breaking typically? or any other typical problems that would cause this?

check the relay first, nc hornet on here had a post on using the napa gpr109 relay. Its a ton cheaper then the gpr110 ours call for. same relayjust the posts are 45 degrees moved but the wires are long enough. I bought one it was like 17 bucks i think. His post listed better ones too. I was on a budget.
advance auto can use the gpr109 andd come up with their product. thats what i did

when replacing my GP's on sunday I noticed that there is some slack in the connection from the gasket to the GP's you may want to check there. In my studies I think I read on here that ford sells a shim kit or something to tighten that up.

Follow my write up on how to troubleshoot the GP system. I sure wish we could get this as a sticky, we have a IPOD sticky but not something that can help all PSD owners. This write up should be a sticky as soon as the weather get's cold. I will post a link below. More than likely it is your GPR and yes you can use a GP109 from Napa, same relay but mounting studs rotated 90 degrees, but the Stancor relay is a much better relay and can be had for under $40. If you are not getting power to one large stud on the GPR at all times check the fuseable link on the starter relay, they can break or get blown, or come loose.

thanks a lot nchornet and jasonz tested the glowplugs and found a few bad, and the relay was also bad. replaced all 8 plugs and put a gpr 109 in for 17 dollers. she starts up mint now. hopefully over christmas i will buy nc's ccv mod and a stancor relay. thanks for all your help tho guys, really a big help. The mods should really make that writeup a sticky!

I am happy to say it is now a sticky thanks to MR. MOD DAVE!!!!! Glad it cured your problem, you wonder if anyone is getting help sometimes. If you look in the 7.3 mod help section I did a write up on the Stancor relay and the Marinco mod, all are good mods to do for cold weather. Just let me know when you are ready for the CCV and Raul and I will get one right out to you, it really makes a big difference in keeping things clean under the hood, something I am a little anal about, lol!!
